NCP1117LPST50T3G-MS from MSKSEMI, 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 for the fixed-output (5.0 V) variant, the reference return for the regulator. |
| 2 | Vout | power_out | Regulated output pin; the 5.0 V fixed-output variant supplies up to 1 A maximum output current. |
| 3 | Vin | power_in | Input pin; the datasheet gives a maximum input voltage of 18 V. |
