LM1117S-1.5

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263

LM1117S-1.5 from HGSEMI, in a TO-263. 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 GND/ADJ power_in Ground pin for the fixed-voltage LM1117-1.5; the datasheet labels this pin GND/ADJ, with ADJ used on the adjustable version.
2 VOUT output Regulated output voltage pin; the datasheet lists the fixed-version output accuracy as 2% (1.5 V typical, 1.47 V to 1.53 V at 10 mA to 1 A with VIN 3.5 V).
3 VIN power_in Input voltage pin; the recommended input voltage is 15 V and the absolute maximum input voltage is 20 V.
