H7533-1

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

H7533-1 from Shanghai Siproin Microelectronics, 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 Device ground / common return for both input and output. Reference for the internal bandgap and feedback network.
2 VIN power_in Unregulated supply input. Absolute max 18V; recommended operating range up to 15V (H7533-1 line-regulation window 4.5V ≤ VIN ≤ 16V). Bypass close to the pin with a small ceramic capacitor.
3 VOUT power_out Regulated 3.3V output (3.234V - 3.366V, ±2%). Sources up to 150mA typical. Requires an output capacitor for stability; low-ESR ceramic recommended.

CAD (KiCad official)

  • Symbol: H7533-1
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: h7533-1-etched.step / h7533-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7533-1.step / h7533-1.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
h7533-1.step 57 KB You want the bare part, or you mark your own boards.
h7533-1-etched.step 994 KB You want the part with H7533-1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 275 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:
