LMS8117AMP-1.8

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

LMS8117AMP-1.8 from Texas Instruments, in a SOT-223-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJUST or GND power_in Ground pin for fixed output versions.
2 OUTPUT output Output voltage (VO) pin for the regulator, 1.8 V at 0 to 1 A load with input 3.2 to 10 V.
3 INPUT input Input voltage (VI) pin for the regulator, requires 3.2 to 10 V for regulation.
4 OUTPUT output Output tab for thermal connection, internally connected to pin 2 output.
