AP7331-25WG-7

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

AP7331-25WG-7 from Diodes Incorporated, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Voltage input pin (2V to 6V). Bypass to ground through at least a 1µF capacitor.
2 GND power_in Ground reference for the regulator.
3 EN input Enable input, active high. VIH ≥ 1.4V turns the regulator on; VIL ≤ 0.4V shuts it down. Do not float; absolute max VIN + 0.3V.
4 NC unconnected No internal connection. Leave floating or tie to GND.
5 OUT power_out Regulated 2.5V output pin, 300mA capable. Bypass to ground through a 1µF ceramic capacitor for stability.

CAD (KiCad official)

  • Symbol: AP7331-25WG-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-25 (KiCad packages3D, STEP)
  • 3D model files: ap7331-25wg-7-etched.step / ap7331-25wg-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7331-25wg-7.step / ap7331-25wg-7.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap7331-25wg-7.step 85 KB You want the bare part, or you mark your own boards.
ap7331-25wg-7-etched.step 2.1 MB You want the part with AP7331-25WG-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 516 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (13 pp, sha256 9fdedb2b73161d34, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
