H7233-1M5R

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

H7233-1M5R from Shanghai Siproin Microelectronics, in a SOT-23-5. 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 VIN power_in Supply voltage input. Operating range 3.5 V to 15 V (absolute max 18 V). Decouple with a 1 µF input capacitor to GND close to the pin.
2 GND power_in Ground / common return (Vss). Connect to system ground.
3 CE input Chip enable input, active high. Drive high to enable the regulator; typically pulled up through ~10 kΩ per the application circuit. Available only on the SOT-23-5 variant.
4 NC unconnected Not connected. Leave floating or tie to a copper island; no internal connection on the SOT-23-5 package.
5 VOUT power_out Regulated 3.3 V output (±2% accuracy), rated for >400 mA. Decouple with a 1 µF output capacitor to GND close to the pin for stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
h7233-1m5r.step 85 KB You want the bare part, or you mark your own boards.
h7233-1m5r-etched.step 1.8 MB You want the part with H7233-1M5R already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 449 faces against 102 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 (11 pp, sha256 a21c635cc1616868, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
