H7650-33PR

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

H7650-33PR 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 VSS power_in Ground / common return for input and output. Tie to system single-point ground.
2 VIN power_in Unregulated supply input, -0.3V to 9V absolute max (recommended <=8V). Requires a 1uF input capacitor (CIN) to VSS close to the pin.
3 VOUT power_out Regulated 3.3V output (tolerance +/-2%), up to 750mA typical output current. Requires a 1uF tantalum or 6.8uF ceramic output capacitor (COUT) to VSS for stability.

Ordering variants

Same part, different packaging or reel option.

  • H7650-33PRG
  • H7650-33PRM5

CAD (KiCad official)

  • Symbol: H7650-33PR
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: h7650-33pr-etched.step / h7650-33pr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7650-33pr.step / h7650-33pr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
h7650-33pr.step 57 KB You want the bare part, or you mark your own boards.
h7650-33pr-etched.step 1.5 MB You want the part with H7650-33PR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 398 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: Shanghai Siproin Microelectronics datasheet (7 pp, sha256 2363f11ce49fd71c, 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).
