ht7533.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

HT7533

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

HT7533 from TWGMC, in a SOT-23. 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. Common return for both input and output currents.
2 VOUT power_out Regulated output. Fixed +3.3V ±3% (3.201-3.399V typical) at up to 100mA. Requires a small output capacitor for stability; typical dropout is 100mV at IOUT=1mA.
3 VIN power_in Unregulated supply input. Absolute maximum +30V; recommended operating range from (VOUT+dropout) up to 24V for line-regulation spec, with headroom needed above the 3.3V output. Bypass to GND with a ceramic capacitor.

CAD (KiCad official)

  • Symbol: HT7533
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ht7533-etched.step / ht7533-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7533.step / ht7533.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7533.step 59 KB You want the bare part, or you mark your own boards.
ht7533-etched.step 1.2 MB You want the part with HT7533 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 289 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: TWGMC datasheet (12 pp, sha256 d0d358ba595fe029, 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).
