AP131-30WG-7

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

AP131-30WG-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 IN power_in Input voltage pin; the datasheet specifies VIN of 2.7V to 5.5V (recommended), with an absolute maximum input voltage of 6V.
2 GND power_in Ground pin for the regulator.
3 EN input Enable pin; the output is ON when EN is at 1.5V to VIN and OFF when EN is at 0V to 0.8V.
4 BP passive Band-gap reference bypass pin; an external capacitor (CBP) connected here reduces output noise.
5 OUT power_out Regulated output voltage pin, guaranteed to supply up to 300mA output current.

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

  • Symbol: AP131-30WG-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: ap131-30wg-7-etched.step / ap131-30wg-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap131-30wg-7.step / ap131-30wg-7.glb are the bare package body.

  • Datasheet: Diodes Incorporated datasheet (7 pp, sha256 7205dd05208f6306, 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.
