AP7315DQ-28W5-7 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 datasheet specifies a VIN range of 1.7V to 5.25V with a 6.0V absolute maximum rating. |
| 2 | GND | power_in | Ground pin, which 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; EN input high is 1.3V to 5.25V and input low is 0V to 0.5V, with a 6.0V absolute maximum rating. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated power output pin; the device guarantees 150mA output current and folds back to approximately 55mA (typical) on a short to ground. |

- Symbol:
AP7315DQ-28W5-7 - Footprint:
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)
