H7225-1M5R

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

H7225-1M5R 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 3.5V to 15V (absolute max 18V). Bypass to GND with a 1µF ceramic/tantalum capacitor close to the pin.
2 GND power_in Ground / reference return (Vss). Connect to the system ground plane.
3 CE input Chip enable input, active-high. Drive high to enable the regulator; drive low to disable and place the device in low-quiescent shutdown. Do not float.
4 NC unconnected No connection. Leave floating or tie to GND per PCB preference.
5 VOUT power_out Regulated 2.5V output (±2%). Delivers up to 400mA typical, 500mA peak with current limiting. Bypass to GND with a 1µF ceramic/tantalum capacitor near the pin for stability.
