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. |
