AP7343DQ-18W5-7 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, with a recommended operating input range of 1.7V to 5.25V and an absolute maximum of 6.0V. |
| 2 | GND | power_in | Ground reference pin; a minimum 0.47μF ceramic input capacitor is recommended between VIN and GND. |
| 3 | EN | input | Enable pin must be driven high or low and must not float; high (VEN of 1.3V to 5.25V) enables the regulator and low (up to 0.5V) puts it into shutdown. |
| 4 | NC | unconnected | Not connected internally; recommended to connect to GND to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Regulated output pin; this AP7343DQ-18 variant has a fixed 1.8V output with guaranteed output current of 300mA. |
