apply when operating the device outside of its rated operating conditions.Note 2:The ESD rating of pins 3and 4for the SOT-23package,or pins 1and 3for the LLP package,is 1kV.Note 3:The maximum allowable power dissipation is a function of the maximum junction temperature,T J (MAX),the junction-to-ambient thermal resistance,θJ-A ,and the ambient temperature,T A .The maximum allowable power dissipation at any ambient temperture is calculated using:Where the value of θJ-A for the SOT-23package is 220˚C/W in a typical PC board mounting and the LLP package is 65˚C/W.Exceeding the maximum allowable dissipation will cause excessive die temperature,and the regulator will go into thermal shutdown.Note 4:If used in a dual-supply system where the regulator load is returned to a negative supply,the LP2992output must be diode-clamped to ground.Note 5:The output PNP structure contains a diode between the V IN to V OUT terminals that is normally reverse-biased.Reversing the polarity from V IN to V OUT will turn on this diode.Note 6:Limits are 100%production tested at 25˚C.Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control (SQC)methods.The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).Note 7:V IN must be the greater of 2.2V or V OUT(nom)+Dropout Voltage to maintain output regulation.Dropout voltage is defined as the input to output differential at which the output voltage drops 2%below the value measured with a 1V differential.Note 8:The ON/OFF input must be properly driven to prevent possible misoperation.For details,refer to Application Hints.Note 9:The LP2992has foldback current limiting which allows a high peak current when V OUT >0.5V,and then reduces the maximum output current as V OUT is forced to ground (see Typical Performance Characteristics curves).LP29925Typical Performance CharacteristicsUnless otherwise specified:C IN =1µF,C OUT =4.7µF,V IN =V

stability.These capacitors must be correctly selected for good performance.Input CapacitorAn input capacitor whose capacitance is ≥1µF is required between the LP2992input and ground (the amount of ca-pacitance may be increased without limit).This capacitor must be located a distance of not more than 1cm from the input pin and returned to a clean analog ground.Any good quality ceramic,tantalum,or film capacitor may be used at the input.Important:Tantalum capacitors can suffer catastrophic fail-ure due to surge current when connected to a low-impedance source of power (like a battery or very large capacitor).If a Tantalum capacitor is used at the input,it must be guaranteed by the manufacturer to have a surge current rating sufficient for the application.There are no requirements for ESR on the input capacitor,but tolerance and temperature coefficient must be consid-ered when selecting the capacitor to ensure the capacitance will be ≥1µF over the entire operating temperature range.Output Capacitor:The LP2992is designed specifically to work with ceramic output capacitors,utilizing circuitry which allows the regula-tor to be stable across the entire range of output current with an output capacitor whose ESR is as low as 5m Ω.It may also be possible to use Tantalum or film capacitors at the output,but these are not as attractive for reasons of size and cost (see next section Capacitor Characteristics).The output capacitor must meet the requirement for mini-mum amount of capacitance and also have an ESR (equiva-lent series resistance)value which is within the stable range.Curves are provided which show the stable ESR range as a function of load current (see ESR graph below).20029407Important:The output capacitor must maintain its ESR within the stable region over the full operating temperature range of the application to assure stability.The LP2992requires a minimum of 4.7µF on the output (output capacitor size can be increased without limit).It is important to remember that capacitor tolerance and variation with temperature must be taken into consideration when selecting an output capacitor so that the minimum required amount of output capacitance is provided over the full operating temperature range.It should be noted thatceramic capacitors can exhibit large changes in capacitance with temperature (see next section,Capacitor Characteris-tics ).The output capacitor must be located not more than 1cm from the output pin and returned to a clean analog ground.Noise Bypass Capacitor:Connecting a 10nF capacitor to the Bypass pin significantly reduces noise on the regulator output.It should be noted that the capacitor is connected directly to a high-impedance cir-cuit in the bandgap reference.Because this circuit has only a few microamperes flowing in it,any significant loading on this node will cause a change in the regulated output voltage.For this reason,DC leakage current through the noise bypass capacitor must never ex-ceed 100nA,and should be kept as low as possible for best output voltage accuracy.The types of capacitors best suited for the noise bypass capacitor are ceramic and film.High-quality ceramic capaci-tors with either NPO or COG dielectric typically have very low leakage.10nF polypropolene and polycarbonate film capacitors are available in small surface-mount packages and typically have extremely low leakage current.CAPACITOR CHARACTERISTICSThe LP2992was designed to work with ceramic capacitors on the output to take advantage of the benefits they offer:for capacitance values in the 2.2µF to 10µF range,ceramics are the least expensive and also have the lowest ESR values (which makes them best for eliminating high-frequency noise).The ESR of a typical 4.7µF ceramic capacitor is in the range of 5m Ωto 10m Ω,which easily meets the ESR limits required for stability by the LP2992.One disadvantage of ceramic capacitors is that their capaci-tance can vary with temperature.Most large value ceramic capacitors (≥2.2µF)are manufactured with the Z5U or Y5V temperature characteristic,which results in the capacitance dropping by more than 50%as the temperature goes from 25˚C to 85˚C.This could cause problems if a 4.7µF capacitor were used on the output since it will drop down to approximately 2.3µF at high ambient temperatures (which could cause the LP2992to oscillate).If Z5U or Y5V capacitors are used on the output,a minimum capacitance value of 10µF must be observed.A better choice for temperature coefficient in ceramic capaci-tors is X7R,which holds the capacitance within ±15%.Un-fortunately,the larger values of capacitance are not offered by all manufacturers in the X7R dielectric.Tantalum:Tantalum capacitors are less desirable than ceramics for use as output capacitors because they are more expensive when comparing equivalent capacitance and voltage ratings in the 1µF to 4.7µF range.Another important consideration is that Tantalum capacitors have higher ESR values than equivalent size ceramics.This means that while it may be possible to find a Tantalum capacitor with an ESR value within the stable range,it would have to be larger in capacitance (which means bigger and more costly)than a ceramic capacitor with the same ESR value.L P 2992 12Application Hints(Continued)It should also be noted that the ESR of a typical Tantalum will increase about2:1as the temperature goes from25˚C down to−40˚C,so some guard band must be allowed.ON/OFF INPUT OPERATIONThe LP2992is shut off by driving the ON/OFF input low,and turned on by pulling it high.If this feature is not to be used, the ON/OFF input should be tied to V IN to keep the regulator output on at all times.To assure proper operation,the signal source used to drive the ON/OFF input must be able to swing above and below the specified turn-on/turn-off voltage thresholds listed in the Electrical Characteristics section under V ON/OFF.To prevent mis-operation,the turn-on(and turn-off)voltage signals ap-plied to the ON/OFF input must have a slew rate which is ≥40mV/µs.Caution:the regulator output voltage can not be guaranteed if a slow-moving AC(or DC)signal is applied that is in the range between the specified turn-on and turn-off voltages listed under the electrical specification V ON/OFF(see Electri-cal Characteristics).REVERSE INPUT-OUTPUT VOLTAGEThe PNP power transistor used as the pass element in the LP2992has an inherent diode connected between the regu-lator output and input.During normal operation(where the input voltage is higher than the output)this diode is reverse-biased.However,if the output is pulled above the input,this diodewill turn ON and current will flow into the regulator output.Insuch cases,a parasitic SCR can latch which will allow a highcurrent to flow into V IN(and out the ground pin),which candamage the part.In any application where the output may be pulled above theinput,an external Schottky diode must be connected fromV IN to V OUT(cathode on V IN,anode on V OUT),to limit thereverse voltage across the LP2992to0.3V(see AbsoluteMaximum Ratings).LLP MountingThe LLP package requires specific mounting techniqueswhich are detailed in National Semiconductor ApplicationNote#1187.Referring to the section PCB Design Recom-mendations,it should be noted that the pad style whichshould be used with the LLP package is the NSMD(non-solder mask defined)type.LP299213Physical Dimensionsinches (millimeters)unless otherwise noted5-Lead Small Outline Package (M5)NS Package Number MF05AFor Order Numbers,refer to Table 1in the
