AP2120N-1.8TRG1 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 | Ground reference for the regulator. Connect directly to the system ground plane; this pin also serves as the reference return for the internal voltage reference and error amplifier. |
| 2 | VOUT | power_out | Regulated output voltage pin (1.8 V fixed for the -1.8 option). Delivers up to 150 mA continuous (250 mA current limit). Requires a minimum 1 μF output capacitor with ESR between 0.01 Ω and 100 Ω for stability; ceramic capacitors are recommended. |
| 3 | VIN | power_in | Unregulated input supply pin. Recommended operating range 2 V to 6 V (absolute max 6.5 V). A 1 μF input bypass capacitor is required close to the pin. |
