LD1117DT33CTR LD1117S50CTR LD1117STR LD1117S33TRThis is information on a product in full production.February 2020DocID2572 Rev 371/46LD1117Adjustable and fixed low drop positive voltage regulatorDatasheet - production dataFeatures•Low dropout voltage (1 V typ.)• 2.85 V device performances are suitable for SCSI-2 active termination •Output current up to 800 mA•Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V, 3.3V, 5.0 V •Adjustable version availability (V REF = 1.25 V)•Internal current and thermal limit•Available in ± 1 % (at 25 °C) and 2 % in full temperature range •Supply voltage rejection: 75 dB (typ.)DescriptionThe LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version(V REF =1.25V). Concerning fixed versions, are offered the following output voltages: 1.2 V, 1.8 V, 2.5 V, 2.85 V, 3.3 V and 5.0 V. The device is supplied in: SOT-223, DPAK, SO-8 and TO-220. The SOT-223 and DPAK surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor. In fact in this case, unlike than PNP one, the quiescent current flows mostly into the load. Only a very common 10 µF minimum capacitor is needed for stability. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1 % at 25 °C. The adjustable LD1117 is pin to pin compatible with the other standard. Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance.Contents LD11172/46DocID2572 Rev 37Contents1Diagram . . . . . . . . . . . . . . . . . . . . . . . . . .

I ADJ is 60 µA typ. (120 µA max.) and ∆I ADJ is 1 µA typ. (5 µA max.).R1 is normally fixed to 120 Ω. From Figure9 we obtain:V OUT = V REF + R2 (I ADJ +I R1) = V REF + R2 (I ADJ +V REF /R1) = V REF (1 + R2 / R1) + R2 x I ADJ.In normal application R2 value is in the range of few kΩ, so the R2 x I ADJ product could notbe considered in the V OUT calculation; then the above expression becomes:V OUT = V REF (1 + R2 / R1).In order to have the better load regulation it is important to realize a good Kelvin connectionof R1 and R2 resistors. In particular R1 connection must be realized very close to OUT andADJ pin, while R2 ground connection must be placed as near as possible to the negativeLoad pin. Ripple rejection can be improved by introducing a 10 µF electrolytic capacitorplaced in parallel to the R2 resistor (see Figure10).DocID2572 Rev 3725/46LD1117Package information8 Package informationIn order to meet environmental requirements, ST offers these devices in different grades of ECOPACK packages, depending on their level of environmental compliance.

MEMORY存储芯片LM1117IMPX-ADJ中文规格书

3 Description
The LM1117 is a low dropout voltage regulator with a dropout of 1.2 V at 800 mA of load current.
The LM1117 is available in an adjustable version, which can set the output voltage from 1.25 to 13.8 V with only two external resistors. In addition, it is available in five fixed voltages, 1.8 V, 2.5 V, 3.3 V, and 5 V.
(2) The maximum power dissipation is a function of TJ(max) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–TA)/RθJA. All numbers apply for packages soldered directly into a PCB.
A minimum of 10-µF tantalum capacitor is required at the output to improve the transient response and stability.
