# AP7375-50SA-7

**DIODES INCORPORATED** · Global Sourcing Parts · SOT-23

AP7375-50SA-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, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input voltage, recommended operating range 3.0 V to 45 V (absolute maximum -0.3 V to 55 V), with a 1 µF ceramic input capacitor recommended close to the pin. |
| 2 | VOUT | power_out | Regulated 5.0 V output for this -50 version (absolute maximum -0.3 V to 6 V), requiring a minimum 1 µF ceramic output capacitor (X7R or X5R) placed as close as possible to VOUT and GND. |
| 3 | GND | power_in | Ground reference, to be connected to the external circuit ground to reduce voltage drop caused by trace impedance. |

## CAD (KiCad official)

- Symbol: `AP7375-50SA-7`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.025 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so 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: `ap7375-50sa-7-etched.step` / `ap7375-50sa-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap7375-50sa-7.step` / `ap7375-50sa-7.glb` are the bare package body.
