AP2125N-3.3TRG1 from Diodes Incorporated, in a SOT-23. 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 | Device ground reference. Connect to system ground plane; also serves as the return for the internal reference and control circuitry. |
| 2 | VOUT | power_out | Regulated 3.3V output (fixed, ±2% accuracy). Sources up to 300mA (min). Requires a 1µF ceramic output capacitor for stability; compatible with low-ESR ceramic capacitors. |
| 3 | VIN | power_in | Unregulated input supply. Recommended VIN = VOUT+0.5V to 6V (absolute max 6.5V). Bypass with a 1µF ceramic capacitor close to the pin. |
