LM1117S-3.3 from HTC Korea TAEJIN Tech, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference and return path, must be connected to system ground plane. |
| 2 | VOUT | output | Regulated 3.3V output voltage (3.234V to 3.366V at 0-1A load), requires 10µF or larger output capacitor for stability. |
| 3 | VIN | power_in | Positive supply input voltage, operating 4.8V to 20V with 1.2V typical dropout at 1A output current. |
