H7550-2MR

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

H7550-2MR 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 Device ground / common return. Single-point GND for input and output bypass capacitors.
2 VOUT power_out Regulated 5.0V output (typ 5.00V, min 4.90V, max 5.10V at IOUT=10mA). Capable of sourcing up to 200mA. Requires 10µF output bypass capacitor to GND for stability.
3 VIN power_in Unregulated input supply, 6V to 35V absolute max (VIN must exceed VOUT+dropout ~10mV @ 1mA). Requires 10µF input bypass capacitor to GND.
