AP7343Q-30W5-7 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 and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input pin; the recommended input voltage range is 1.7V to 5.25V, with a 6.0V absolute maximum input voltage. |
| 2 | GND | power_in | Ground reference pin, which the datasheet says should be connected to the external circuit ground to reduce voltage drop caused by trace impedance. |
| 3 | EN | input | Enable pin that must be driven high or low and must not float; high (minimum 1.3V) enables the regulator, low (maximum 0.5V) puts it into shutdown, and the absolute maximum is 6.0V. |
| 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 for the fixed-voltage versions (0.9V to 3.6V); on a short to GND, output current is clamped to approximately 60mA. |

Package_TO_SOT_SMD:SOT-23-5 - 3D model: SOT-25, generated on the KiCad land (body 1.6 x 3 mm, terminals on the pads, 1.15 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
