AP7331-28WG-7 from Diodes Incorporated, in a SOT-25. 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 | IN | power_in | Voltage input pin; bypass to ground through at least a 1µF capacitor. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable input, active high; the regulator is turned on when EN is set to logic high. |
| 4 | NC | unconnected | No connection on the SOT25 fixed-output package. |
| 5 | OUT | power_out | Voltage output pin; bypass to ground through a 1µF ceramic capacitor. |
