AP7343Q-11W5-7 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; the absolute maximum input voltage is 6.0 V and the input capacitor should sit as close to the device as possible. |
| 2 | GND | power_in | Ground pin; wide copper traces are required for both VIN and GND pins to keep the input path low-impedance. |
| 3 | EN | input | Enable pin that must be driven either high or low and must not be floating; driving it high enables the regulator, pulling it low puts the regulator into shutdown, and its absolute maximum voltage is 6.0 V. |
| 4 | NC | unconnected | Not connected internally; the datasheet recommends connecting it to GND to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Regulated power output pin with an output voltage range of -0.3 V to VIN + 0.3 V. |
