H7144-1

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

H7144-1 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 / common return for the regulator. Tied to the negative rail of both the input and output decoupling capacitors at a single-point ground.
2 VOUT power_out Regulated 4.4V output (min 4.312V, max 4.488V at IOUT=10mA). Sources up to 50mA (typ 30mA). Requires a 10µF output capacitor (CL) to the single-point GND for stability.
3 VIN power_in Unregulated input supply, 5.4V to 15V for normal operation (18V absolute max, -0.3V min). Requires a 10µF input capacitor (Cin) to GND. Dropout is ~20mV typical at IOUT=1mA.

CAD (KiCad official)

  • Symbol: H7144-1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: h7144-1-etched.step / h7144-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h7144-1.step / h7144-1.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 b56d63e4e3666e63, 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).
