AP7387-30SA-7

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-23

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)
  • 3D model files: ap7387-30sa-7-etched.step / ap7387-30sa-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7387-30sa-7.step / ap7387-30sa-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (18 pp, sha256 8ba9ec885c56ce12, 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).
