H7651-33PR

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

H7651-33PR 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 reference for the regulator. Connect to system ground; the input and output decoupling capacitors return to this node.
2 VIN power_in Unregulated input supply, -0.3V to 8.5V absolute max. Requires a 1µF input capacitor (CIN) to VSS for stability.
3 VOUT power_out Regulated 3.3V output (H7651-33 variant), tolerance ±2%, up to 1A output current with typical dropout ~60mV at 100mA. Requires a 1µF tantalum or 6.8µF ceramic output capacitor (COUT) to VSS.

CAD (KiCad official)

  • Symbol: H7651-33PR
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: h7651-33pr-etched.step / h7651-33pr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7651-33pr.step / h7651-33pr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Shanghai Siproin Microelectronics datasheet (None pp, sha256 0a8ae5124048726e, 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).
