**Diodes Incorporated** · Linear Voltage Regulators (LDO) · SOT-25

AP7383-30WR-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 connection for the regulator. |
| 2 | VIN | power_in | Input voltage pin; recommended supply range is 3.5 V to 30 V, with an absolute maximum of 33 V. |
| 3 | VOUT | power_out | Regulated output voltage pin (3.0 V fixed version for this part). |
| 4 | NC | unconnected | Not connected for the fixed version; not connected internally, and connection to GND is recommended to maximize PCB copper for thermal dissipation. |
| 5 | NC | unconnected | Not connected for the fixed version; not connected internally, and connection to GND is recommended to maximize PCB copper for thermal dissipation. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `AP7383-30WR-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)
- 3D model files: `ap7383-30wr-7-etched.step` / `ap7383-30wr-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap7383-30wr-7.step` / `ap7383-30wr-7.glb` are the bare package body.
