LM1117RS-2.5 from HTC Korea TAEJIN Tech, in a TO-252. 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 reference for the fixed 2.5V version; the datasheet labels this pin 'ADJ / GND' and it serves as the adjust pin only in the adjustable version. |
| 2 | VOUT | power_out | Regulated 2.5V output with up to 1.0A output current, and a 10µF or larger output capacitor is needed for stability. |
| 3 | VIN | power_in | Unregulated input supply with an absolute maximum of 20V and an operating input voltage of 12V for the 2.5V version, with a dropout of 1.2V at 1.0A. |
