For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,or visit Maxim's website at .General DescriptionThe MAX1818 low-dropout linear regulator operates from a +2.5V to +5.5V supply and delivers a guaran-teed 500mA load current with low 120mV dropout. The high-accuracy (±1%) output voltage is preset at an internally trimmed voltage (see Selector Guide ) or can be adjusted from 1.25V to 5.0V with an external resis-tive divider.An internal PMOS pass transistor allows the low 125µA supply current to remain independent of load, making this device ideal for portable battery-operated equip-ment such as personal digital assistants (PDAs), cellu-lar phones, cordless phones, base stations, and notebook computers.Other features include an active-low open-drain reset output that indicates when the output is out of regula-tion, a 0.1µA shutdown, short-circuit protection, and thermal shutdown protection. The device is available in a miniature 800mW 6-pin SOT23 package.ApplicationsNotebook ComputersCellular and Cordless Telephones Personal Digital Assistants (PDAs)Palmtop Computers Base Stations USB Hubs Docking StationsFeatures♦Guaranteed 500mA Output Current ♦Low 120mV Dropout at 500mA♦±1% Output Voltage AccuracyPreset at 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, 5V Adjustable from 1.25V to 5.0V ♦Power OK Output♦Low 125µA Ground Current ♦0.1µA Shutdown Current ♦Thermal Overload Protection ♦Output Current Limit♦Tiny 800mW 6-Pin SOT23 PackageMAX1818500mA Low-DropoutLinear Regulator in SOT23________________________________________________________________Maxim Integrated Products 119-1860; Rev 2; 6/08Ordering Information*Insert the desired two-digit suffix (see Selector Guide) into the blanks to complete the part number.Typical Operating CircuitPin ConfigurationNote :The MAX1818 requires a special solder temperature profile described in the Absolute Maximum Ratings section.T = Tape and reel.#Denotes an RoHS-compliant package.Selector Guide appears at end of data sheet.M A X 1818500mA Low-DropoutLinear Regulator in SOT23ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Copper should be equally shared between the IN, OUT, and GND pins.Note 2:This device is constructed using a unique set of packaging techniques that imposes a limit on the thermal profile to whichthe device can be exposed during board-level solder attach and rework. The limit permits only the use of the solder profiles recommended in the industry standard specification, IPC JEDEC-J-STD-020A, paragraph 7.6, Table 3 for the IR/VPR and convection reflow. Preheating is required. Hand or wave soldering is not allowed.MAX1818500mA Low-DropoutLinear Regulator in SOT23_______________________________________________________________________________________3ELECTRICAL CHARACTERISTICS (continued)Note 4:The Dropout Voltage is defined as V IN - V OUT , when V OUT is 100mV below the value of V OUT measured for V IN = V OUT(NOM)+ 500mV. Since the minimum input voltage is 2.5V, this specification is only meaningful when V OUT(NOM)> 2.5V. For V OUT(NOM)between 2.5V and 3.5V, use the following equations: Typical Dropout = -93mV/V ✕V OUT(NOM)+ 445mV;Guaranteed Maximum Dropout = -137mV/V ✕V OUT(NOM)+7004mV. For V OUT(NOM)> 3.5V, Typical Dropout = 120mV;Maximum Dropout = 220mV.Typical Operating Characteristics(V IN = (V OUT + 500mV) or +2.5V, whichever is greater; SHDN = IN, C IN = 1µF, C OUT = 3.3µF, T A = +25°C, unless otherwise noted.)5025125100751501752252002500 1.0 1.50.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5GROUND PIN CURRENT vs. INPUT VOLTAGEINPUT VOLTAGE (V)G R O U N D P I N C U R R E N T (μA )4070558513014511510016000.20.30.40.50.10.60.70.80.9 1.0LOAD CURRENT (A)G R O U N D P I N C U R R E N T (μA )GROUND PIN CURRENT vs. LOAD CURRENT110130120150140160170-4010-15356085TEMPERATURE (°C)G R O U N D P I N C U R R E N T (μA )GROUND PIN CURRENT vs. TEMPERATUREM A X 1818500mA Low-DropoutLinear Regulator in SOT234_______________________________________________________________________________________Typical Operating Characteristics (continued)(V IN = (V OUT + 500mV) or +2.5V, whichever is greater; SHDN = IN, C IN = 1µF, C OUT = 3.3µF, T A = +25°C, unless otherwise noted.)060301209015018000.20.10.30.40.5LOAD CURRENT (A)D R O P O U T V O L T A GE (m V )DROPOUT VOLTAGE vs. LOAD CURRENT-3.0-2.0-2.5-1.5-1.0-0.500.51.01.52.02.53.0LOAD CURRENT (A)O U T P U T V O L T A G E A C C U R A C Y (%)0.20.30.40.10.50.60.70.90.8 1.0OUTPUT VOLTAGE ACCURACYvs. LOAD CURRENT-3.0-2.0-2.5-1.5-1.0-0.500.51.01.52.02.53.0-40-1510356085TEMPERATURE (°C)O U T P U T V O L T A G E A C C U R A C Y (%)OUTPUT VOLTAGE ACCURACYvs. TEMPERATUREPOWER-SUPPLY REJECTION RATIOvs. FREQUENCY8002010P S R R (d B )40305060700.010.11101001000FREQUENCY (kHz)LINE TRANSIENTMAX1818 toc08V INV OUT2.5V 10m V /d i v3.5V 100μs/div500m V /d i vLOAD-TRANSIENT RESPONSEMAX1818 toc09I OUTV OUT500mA 100mA20m V /d i v40μs/divV IN = 3.3V V OUT = 2.5V LOAD-TRANSIENT RESPONSENEAR DROPOUTMAX1818 toc10V O U T 100m V /d i v200m A 0I O U T10μs/div V IN = V OUT + 100mV V OUT = 3.3VPOWER-ON RESETMAX1818 toc11V INV POKV OUT2V/div10ms/divMAX1818500mA Low-DropoutLinear Regulator in SOT23_______________________________________________________________________________________5SHUTDOWN WAVEFORMMAX1818 toc12POK SHUTDOWN VOLTAGEV OUT02V/div200μs/div1.001.011.021.031.041.051.061.071.081.091.101.112.53.03.54.04.55.05.5SHORT-CIRCUIT CURRENT LIMITvs. SUPPLY VOLTAGESUPPLY VOLTAGE (V)S H O R T -C I R C U I T C U R R E N T L I M I T (A )The MAX1818 is a low-dropout, low-quiescent-current linear regulator designed primarily for battery-powered applications. The device supplies loads up to 500mA and is available with preset output voltages. As illustrat-ed in Figure 1, the MAX1818 consists of a 1.25V refer-ence, error amplifier, P-channel pass transistor, and internal feedback voltage-divider.The 1.25V reference is connected to the error amplifier,which compares this reference with the feedback volt-age and amplifies the difference. If the feedback volt-age is lower than the reference voltage, thevoltage. If the feedback voltage is too high, the pass-transistor gate is pulled up, allowing less current to pass to the output.The output voltage is fed back through either an inter-nal resistive divider connected to OUT or an external resistor network connected to SE T. The Dual Mode comparator examines V SET and selects the feedback path. If V SET is below 50mV, the internal feedback path is used and the output is regulated to the factory-preset voltage.Pin DescriptionTypical Operating Characteristics (continued)(V IN = (V OUT + 500mV) or +2.5V, whichever is greater; SHDN = IN, C IN = 1µF, C OUT = 3.3µF, T A = +25°C, unless otherwise noted.)M A X 1818500mA Low-DropoutLinear Regulator in SOT236_______________________________________________________________________________________Additional blocks include an output current limiter, ther-mal sensor, and shutdown logic.Internal P-Channel Pass TransistorThe MAX1818 features a 0.25ΩP-channel MOSFE T pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive,which reduces quiescent current. PNP-based regula-tors also waste considerable current in dropout when the pass transistor saturates, and use high base-drive currents under large loads. The MAX1818 does not suf-fer from these problems and consumes only 125µA of quiescent current under heavy loads as well as in dropout.Output Voltage SelectionThe MAX1818’s Dual Mode operation allows operation in either a preset voltage mode or an adjustable mode.Connect SE T to GND to select the preset output volt-age. The two-digit part number suffix identifies the out-put voltage (see Selector Guide). For example, the MAX1818EUT33 has a preset 3.3V output voltage.The output voltage may also be adjusted by connecting a voltage-divider from OUT to SE T to GND (Figure 2).Select R2 in the 25k Ωto 100k Ωrange. Calculate R1with the following equation:R1 = R2 [(V OUT / V SET ) – 1]where V SET = 1.25V, and V OUT may range from 1.25V to 5.0V.ShutdownPull SHDN low to enter shutdown. During shutdown, the output is disconnected from the input and supply cur-rent drops to 0.1µA. When in shutdown, POK pulls low and OUT is high impedance. The capacitance and load at OUT determine the rate at which V OUT decays.SHDN can be pulled as high as 6V, regardless of the input and output voltage.Figure 1. Functional DiagramPOK OutputThe power OK (POK) output pulls low when OUT is less than 93% of the nominal regulation voltage. Once OUT exceeds 93% of the nominal voltage, POK goes high impedance. POK is an open-drain N-channel output. To obtain a voltage output, connect a pullup resistor from POK to OUT. A 100k Ωresistor works well for most appli-cations. POK can be used as a power-okay (POK) signal to a microcontroller (µC), or drive an external LED to indi-cate power failure. When the MAX1818 is shut down,POK is held low independent of the output voltage. If unused, leave POK grounded or unconnected.Current LimitThe MAX1818 monitors and controls the pass transis-tor’s gate voltage, limiting the output current to 0.8A (typ). This current limit doubles when the output voltage is within 4% of the nominal value to improve perfor-mance with large load transients.Thermal Overload ProtectionThermal overload protection limits total power dissipa-tion in the MAX1818. When the junction temperature exceeds T J = +170°C, a thermal sensor turns off the pass transistor, allowing the IC to cool. The thermal sensor turns the pass transistor on again after the junc-tion temperature cools by 20°C, resulting in a pulsed output during continuous thermal overload conditions.Thermal overload protection protects the MAX1818 in the event of fault conditions. For continuous operation,do not exceed the absolute maximum junction-temper-ature rating of T J = +150°C.Operating Region and Power DissipationThe MAX1818’s maximum power dissipation depends on the thermal resistance of the IC package and circuit board, the temperature difference between the die junction and ambient air, and the rate of air flow. The power dissipated in the device is P = I OUT ×(V IN -V OUT ). The maximum allowed power dissipation is 800mW at T A = +70°C or:P MAX = (T J(MAX)- T A ) / ( θJC + θCA )where T J - T A is the temperature difference between the MAX1818 die junction and the surrounding air, θJC is the thermal resistance of the junction to the case,and θCA is the thermal resistance from the case through the PC board, copper traces, and other materi-als to the surrounding air. For best heatsinking, the copper area should be equally shared between the IN,OUT, and GND pins.The MAX1818 delivers up to 0.5A RMS and operates with input voltages up to +5.5V, but not simultaneously.High output currents can only be sustained when input-output differential voltages are low, as shown in Figure 3.MAX1818500mA Low-DropoutLinear Regulator in SOT23_______________________________________________________________________________________7Figure 2. Adjustable Output Using External Feedback ResistorsApplications InformationCapacitor Selection andRegulator StabilityCapacitors are required at the MAX1818’s input and output for stable operation over the full temperature range and with load currents up to 500mA. Connect a 1µF capacitor between IN and ground and a 3.3µF low-E SR capacitor between OUT and ground. For output voltages less than 2V, use a 4.7µF low-E SR output capacitor. The input capacitor (C IN ) lowers the source impedance of the input supply. Reduce noise and improve load-transient response, stability, and power-supply rejection by using larger output capacitors, such as 10µF.The output capacitor’s (C OUT ) equivalent series resis-tance (ESR) affects stability and output noise. Use out-put capacitors with an E SR of 0.1Ωor less to ensure stability and optimum transient response. Surface-mount ceramic capacitors have very low E SR and are commonly available in values up to 10µF. Connect C IN and C OUT as close to the MAX1818 as possible to mini-mize the impact of PC board trace inductance.Noise, PSRR, and Transient ResponseThe MAX1818 is designed to operate with low dropout voltages and low quiescent currents in battery-powered systems while still maintaining good noise, transient response, and AC rejection. See the T ypical Operating Characteristics for a plot of power-supply rejection ratio (PSRR) versus frequency. When operating from noisy sources, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors and through passive filtering techniques.The MAX1818 load-transient response (see T ypical Operating Characteristics ) shows two components of the output response: a DC shift from the output imped-ance due to the load current change, and the transient response. A typical transient response for a step change in the load current from 100mA to 500mA is 8mV. Increasing the output capacitor’s value and decreasing the ESR attenuates the overshoot.Input-Output (Dropout) VoltageA regulator’s minimum input-to-output voltage differen-tial (dropout voltage) determines the lowest usable sup-ply voltage. In battery-powered systems, this determines the useful end-of-life battery voltage.Because the MAX1818 uses a P-channel MOSFET pass transistor, its dropout voltage is a function of drain-to-source on-resistance (R DS(ON)) multiplied by the load current (see Typical Operating Characteristics ).V DROPOUT = V IN - V OUT = R DS(ON)× I OUTThe MAX1818 ground current remains below 150µA in dropout.M A X 18188_______________________________________________________________________________________500mA Low-DropoutLinear Regulator in SOT23Selector GuideChip InformationTRANSISTOR COUNT: 845Package InformationFor the latest package outline information and land patterns, go to /packages .MAX1818500mA Low-DropoutLinear Regulator in SOT23Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.

Using the ADM181x series ensures that there are typically 150 ms for the power supply to stabilize before the system is reset and safe system initialization begins.The ADM181x series of microprocessor reset circuits are avail-able in low cost, space-saving SOT-23 packages.ADM1810–ADM1813/ADM1815–ADM1818–SPECIFICATIONS(T A = –40؇C to +85؇C unless otherwise noted)Parameter Min Typ Max Units Test Conditions/NoteSUPPLYVoltage 1.2 5.5VCurrent3040µA(ADM1810/ADM1811/ADM1813)V CC < 5.5 V, RST Output Open3040µA(ADM1812) V CC < 5.5 V2835µA(ADM1815/ADM1816/ADM1817/ADM1818)V CC < 5.5 V, RST Output OpenOUTPUT CURRENT8mA@ 0.4 V, V CC≥ 2.7 V*350µA(ADM1810/ADM1812/ADM1815/ADM1817)@ 2.4 V, V CC≥ 2.7 VOUTPUT VOLTAGE V CC – 0.5V CC – 0.1V(ADM1810/ADM1812/ADM1815/ADM1817)@ 0 µA to 500 µAV CC TRIP-POINTADM1810-5, ADM1810-10, ADM1810-15/ADM1811/ADM1812/ADM1813-5 4.50 4.62 4.75V(5%)ADM1811/ADM1812/ADM1813-10 4.25 4.35 4.49V(10%)ADM1811/ADM1812/ADM1813-15 4.00 4.13 4.24V(15%)ADM1815/ADM1816/ADM1817/ADM1818-5 2.98 3.06 3.15V(5%)ADM1815/ADM1816/ADM1817/ADM1818-10 2.80 2.88 2.97V(10%)ADM1815/ADM1816/ADM1817/ADM1818-20 2.47 2.55 2.64V(20%)INTERNAL PULL-UP RESISTORADM1811/ADM1813/ADM1816/ADM1818 3.5 5.57.5kΩOUTPUT CAPACITANCE10pFRESET ACTIVE TIME100150300msV CC DETECT TO RSTFalling510µs(ADM1810/ADM1811/ADM1812/ADM1813)715µs(ADM1815/ADM1816/ADM1817/ADM1818) Rising100150300ms t R = 5 µsPUSH-BUTTON DETECT TO RST1µs(ADM1813/ADM1818)PUSH-BUTTON RESET100150300ms(ADM1818) 2.7 V ≤ V CC≤ 3.3 V100150300ms(ADM1813)NOTES*For ADM181x-20, V CC = V CCTP, sink current reduces to 8 mA.Specifications subject to change without notice.REV. 0–2–REV. 0ADM1810–ADM1813/ADM1815–ADM1818–3–ORDERING GUIDENOTESRL7 or REEL7 are in reels of 3000 parts.

Pressing this switch will pull the reset output low. If the push-button reset button pulls the RST output low for a period greater than 1 µs, then, when the reset button releases the RST line to float high, the RST line will stay low for a further 150 ms typical.Figure 4.Push-Button Reset Timing DiagramThe ADM1818 range has options which allow the user to monitor 3.3 V supplies with 10% and 20% tolerance options.While the ADM1813 range has options which allow the user to monitor 5 V supplies with 5%, 10% and a 15% tolerance options.ADM1810, ADM1812, ADM1815 AND ADM1817The ADM1812 is a 5 V low cost voltage monitor with an active high push-pull output. The ADM1812 supports 5%, 10% and15% tolerances. The ADM1810 is similar to the ADM1812,except that the ADM1810 has an active low push-pull output.The ADM1817 is 3.3 V voltage monitor with an active high push-pull output. The ADM1817 supports 5%, 10% and 20%tolerances. The ADM1815 is similar to the ADM1817, except that the ADM1815 has an active low push-pull output.The ADM1810/ADM1812/ADM1815/ADM1817 can be con-nected directly to most microprocessor-reset inputs without the need for external components.Figure 5.ADM1810/ADM1812/ADM1815/ADM1817Typical ApplicationOUTLINE DIMENSIONSDimensions shown in inches and (mm).3-Lead Plastic Surface Mount Package (SOT-23)(RT-3)ADM1811 AND ADM1816The ADM1811 is a low cost voltage monitor with an open drain output. The ADM1811 is designed to monitor 5 V supplies.The ADM1811 range comes in three different variants which allow the monitoring of a 5 V supply with a tolerance of 5%,10% and 15%. The ADM1816 is a 3.3 V version of the ADM1811and supports 5%, 10% and 20% tolerance options.Figure 6.ADM1811/ADM1816 Typical Application。
