SD5088A25S

SHOUDING · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

SD5088A25S from SHOUDING, in a SOT-23-3. 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 Vss power_in Ground / return pin. Connect to system ground.
2 Vout power_out Regulated 2.5V output. Supplies up to 300mA. Requires a 1µF (typ.) output capacitor to ground for stability.
3 Vin power_in Unregulated supply input. Absolute max 6.5V. Typical bypass capacitor 1µF to Vss. Must be at least Vout+dropout for regulation.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: SD5088A25S
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: sd5088a25s-etched.step / sd5088a25s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd5088a25s.step / sd5088a25s.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sd5088a25s.step 59 KB You want the bare part, or you mark your own boards.
sd5088a25s-etched.step 2.4 MB You want the part with SD5088A25S already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 547 faces against 69 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: SHOUDING datasheet (9 pp, sha256 6caae5d10f027a64, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
