NCP1117LPST33T3G-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 version (3.3V); the Adj. pin on the adjustable version occupies this position. |
| 2 | VOUT | power_out | Regulated 3.3V output (±2% accuracy, up to 1A maximum output current). |
| 3 | VIN | power_in | Input supply pin; absolute maximum input voltage is 18V. |
