AP7315DQ-29W5-7 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 recommended input voltage range is 1.7V to 5.25V, and the absolute maximum input voltage is 6.0V. |
| 2 | GND | power_in | Ground pin; it should be connected to the external circuit ground with a wide trace to limit voltage drop from trace impedance. |
| 3 | EN | input | Enable pin that must be driven high or low and must not float; high (1.3V to 5.25V) enables the regulator and low (0V to 0.5V) puts it into shutdown. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated power output; with a short to GND, short-circuit protection clamps the output current to approximately 60mA. |
