AP7351D-28W5-7

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

AP7351D-28W5-7 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 VIN power_in Power input pin, with input voltage specified from 1.4V to 5.5V (absolute maximum 6.0V).
2 GND power_in Ground pin, which should be connected to the external circuit ground to reduce voltage drop caused by trace impedance.
3 EN input Enable pin that must be driven high or low and must not float; high (at least 1.0V, up to 5.5V) enables the regulator and low (6.0V absolute maximum, 0.4V maximum for logic low) puts it into shutdown.
4 NC unconnected No connection for fixed VOUT versions.
5 VOUT power_out Regulated output voltage pin, rated for up to 150mA output current with ±1% VOUT accuracy above 2.0V.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

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

  • Symbol: AP7351D-28W5-7
  • 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: ap7351d-28w5-7-etched.step / ap7351d-28w5-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7351d-28w5-7.step / ap7351d-28w5-7.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (18 pp, sha256 4cd3008f2ae9a291, 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).
