HT7133-1

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

HT7133-1 from UMW, in a SOT-89. 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 (0V) for the regulator. Connect to the system ground plane; the input and output decoupling capacitors return here.
2 VIN power_in Unregulated input supply, up to 30V absolute maximum. Bypass with a 10µF capacitor (C1) to GND close to the pin per the application circuit.
3 VOUT power_out Regulated 3.3V output (±3%, tested at VIN=5.5V, IOUT=10mA). Rated 60mA typical / 100mA max output current; requires a 10µF (C2) output capacitor to GND for stability.

CAD (KiCad official)

  • Symbol: HT7133-1
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: ht7133-1-etched.step / ht7133-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7133-1.step / ht7133-1.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7133-1.step 57 KB You want the bare part, or you mark your own boards.
ht7133-1-etched.step 927 KB You want the part with HT7133-1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 268 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 (14 pp, sha256 ae108c17cf1258c8, 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).
