H7605-33MR

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

H7605-33MR from Shanghai Siproin Microelectronics, 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 / VSS reference for the regulator. Connect to system ground; the 1uF ceramic input and output bypass capacitors return here.
2 VOUT power_out Regulated 3.3V output (tolerance +/-2%, Vout x 0.98 to Vout x 1.02). Rated 300mA (limited by package power dissipation, Pd = 0.20W for SOT23-3). Requires >=1uF low-ESR ceramic output capacitor for stability.
3 VIN power_in Unregulated supply input. Operating range typ 6V, absolute max 10V; recommended Vin = Vout + 1V for regulation (dropout ~0.19V typ / 0.35V max at 100mA for Vout >= 2.8V). Bypass with 1uF ceramic capacitor to GND.

CAD (KiCad official)

  • Symbol: H7605-33MR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: h7605-33mr-etched.step / h7605-33mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7605-33mr.step / h7605-33mr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
h7605-33mr.step 59 KB You want the bare part, or you mark your own boards.
h7605-33mr-etched.step 1.9 MB You want the part with H7605-33MR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 458 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:
