H7225-1

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

H7225-1 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 Device ground (Vss) reference. Connect to system ground with a low-impedance path.
2 VIN power_in Regulator input supply. Absolute max -0.3V to 18V; operating range 3.5V-15V. Bypass with 1uF ceramic/tantalum input capacitor (CIN) close to the pin.
3 VOUT power_out Regulated 2.5V output (±2%), sourcing up to >400mA. Requires a 1uF tantalum or 6.8uF ceramic output capacitor to ground for stability.
