HT7533-1

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

HT7533-1 from UMW, in a SOT-89. Pinout and pin descriptions extracted from the 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. Common return for input and output currents.
2 VIN power_in Unregulated input supply, up to 30V absolute maximum. For HT7533-1, typical operation at VIN=5.5V with recommended range 4.5V to 30V. Bypass to GND with a ceramic capacitor near the pin.
3 VOUT power_out Regulated 3.3V output (±3%, range 3.201V-3.399V typ). Delivers up to 100mA (60mA min guaranteed). Requires an output ceramic capacitor for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7533-1.step 57 KB You want the bare part, or you mark your own boards.
ht7533-1-etched.step 1.0 MB You want the part with HT7533-1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 287 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 (15 pp, sha256 8a1946363b661b62, 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).
