AP7383-345WR-7

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AP7383-345WR-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 Input voltage pin; the 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, fixed at 3.45 V for this 345 version.
4 NC unconnected Not connected internally; the datasheet recommends connecting it to GND to maximize PCB copper for thermal dissipation.
5 NC unconnected Not connected internally; the datasheet recommends connecting it to GND to maximize PCB copper for thermal dissipation.

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

  • Symbol: AP7383-345WR-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: ap7383-345wr-7-etched.step / ap7383-345wr-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7383-345wr-7.step / ap7383-345wr-7.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (13 pp, sha256 ba4342c8e55d91d5, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
