AP2114HA-1.8TRG1 from Diodes Incorporated, 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 | VIN | power_in | Input voltage pin; recommended supply range is 2.5 V to 6.0 V, with an absolute maximum of 6.5 V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | VOUT | power_out | Regulated 1.8 V output; the datasheet states stability with a 4.7 µF capacitor (ceramic, tantalum, or aluminum electrolytic). |
