AP7343DQ-12W5-7 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 | VIN | power_in | Power input pin, operating range 1.7V to 5.25V. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin that must be driven high or low and must not float; high enables the regulator and low puts it into shutdown mode. |
| 4 | NC | unconnected | Not connected internally; recommended to connect to GND to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Power output pin of the regulator, up to 300mA guaranteed output current. |
