H7230-1

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

H7230-1 from Shanghai Siproin Microelectronics, in a SOT-23-3. 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 Ground reference (Vss). Connect to system ground; internal voltage reference and error amplifier are referenced to this pin.
2 VOUT power_out Regulated 3.0V output (±2%). Rated for continuous output current up to 400mA at Vin-Vout=1V. Requires a 1uF tantalum or 6.8uF ceramic output capacitor to ground for stability.
3 VIN power_in Unregulated supply input, 3.5V to 15V operating (absolute max 18V). Recommend a 1uF input capacitor to ground close to the pin.

  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: h7230-1-etched.step / h7230-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7230-1.step / h7230-1.glb are the bare package body.

Provenance

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

  • Datasheet: Shanghai Siproin Microelectronics datasheet (9 pp, sha256 2df0180fb7063165, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
