AP7315DQ-33W5-7 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, and the absolute maximum input voltage is 6.0V. |
| 2 | GND | power_in | Ground pin, which should be connected to the external circuit ground to reduce voltage drop from trace 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 and pulling it low shuts it down, with EN high at 1.3V minimum and EN low at 0.5V maximum. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated power output pin; if VOUT is shorted to GND, the short-circuit protection clamps the output current to approximately 60mA. |

Package_TO_SOT_SMD:SOT-23-5 - 3D model: SOT-25, generated on the KiCad land (body 1.6 x 2.8 mm, terminals on the pads, 1.1 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)
