LR1117DSX from LRC, in a SOT-223. 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 | power_in | Ground pin of the fixed-voltage version; the datasheet names it only as Ground and gives no electrical limit for it. |
| 2 | Vout | power_out | Regulated output for the fixed versions (1.2V, 1.8V, 2.5V, 2.85V, 3.3V, 5V, ±2%), rated for a maximum output current of 1.4A and used with a 10uF tantalum or MLCC output capacitor. |
| 3 | Vin | power_in | Input supply pin with a maximum input voltage of 15V under recommended operating conditions, used with a 10uF input capacitor. |
