HT7333-A

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

HT7333-A from UMW, in a SOT-89-3. 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 GND power_in Ground reference for the regulator. All output voltages are referenced to this pin.
2 VOUT power_out Regulated 3.3 V output (tolerance ±3 %, typical 3.3 V, min 3.201 V / max 3.399 V at VIN=4.3 V, IOUT=40 mA). Supplies ≥250 mA. A ceramic output capacitor is recommended for stability.
3 VIN power_in Unregulated supply input. Operating range up to 12 V (absolute maximum 15 V, minimum -0.5 V). An input bypass capacitor is recommended.

CAD (KiCad official)

  • Symbol: HT7333-A
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: ht7333-a-etched.step / ht7333-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7333-a.step / ht7333-a.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7333-a.step 57 KB You want the bare part, or you mark your own boards.
ht7333-a-etched.step 1.1 MB You want the part with HT7333-A already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 296 faces against 42 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: UMW datasheet (12 pp, sha256 3d411e577f5a4887, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
