HT7530S

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

HT7530S from UMW, 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 Device ground / negative supply return. Tie to the system ground plane; the pin also carries the internal reference return.
2 VIN power_in Unregulated input supply. Absolute maximum 30 V; for the 7530 variant typical operating input is 5 V with 4 V ≤ VIN ≤ 30 V for line-regulation spec. Bypass with a 10 µF capacitor to GND close to the pin.
3 VOUT power_out Regulated 3.0 V ±3% output (2.91-3.09 V, VIN = 5 V, IOUT = 10 mA). Rated 60 mA min / 100 mA typ output current; requires a 10 µF output capacitor to GND for stability.

CAD (KiCad official)

  • Symbol: HT7530S
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ht7530s-etched.step / ht7530s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7530s.step / ht7530s.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7530s.step 59 KB You want the bare part, or you mark your own boards.
ht7530s-etched.step 1.4 MB You want the part with HT7530S already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 338 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: UMW datasheet (15 pp, sha256 c8d27849b87576cd, 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).
