H7525-H#

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

H7525-H# from Shanghai Siproin Microelectronics, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the regulator, shared by input and output.
2 VIN power_in Supply input accepting 4.75V to 40V in operation (absolute maximum 45V), with a 10uF input capacitor used in the specifications.
3 VOUT power_out Regulated 2.5V output (±2% accuracy) delivering 100mA typical, with a 10uF output capacitor used in the specifications.
