AP7370-33WR-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 | GND | power_in | Ground reference pin for the regulator. |
| 2 | VIN | power_in | Supply input voltage; the recommended operating range is 3.2V to 18V and the absolute maximum rating is 20V. |
| 3 | VOUT | power_out | Regulated output voltage; output current is rated to 500mA absolute maximum. |
| 4 | NC | unconnected | Not connected for the fixed-output version. |
| 5 | NC | unconnected | Not connected for the fixed-output version. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
AP7370-33WR-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)
