AP7387-30SA-7 from Diodes Incorporated, in a SOT-23. 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 pin, which should be connected to the external circuit ground to reduce voltage drop caused by trace impedance. |
| 2 | VOUT | power_out | Regulated output voltage pin, with a fixed output of 3.0 V to 5 V across versions, requiring a minimum 10 µF ceramic output capacitor for stability. |
| 3 | VIN | power_in | Input voltage pin, with a recommended supply range of 5.0 V to 60 V (absolute maximum -0.3 to 80 V) and a 1 µF input capacitor recommended between VIN and GND. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
AP7387-30SA-7 - Footprint:
Package_TO_SOT_SMD:SOT-23 - 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 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)
