H7651-50PR

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

H7651-50PR from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 VSS power_in Ground reference for the regulator. Connect to system ground; return path for input and output currents.
2 VIN power_in Unregulated supply input, up to 8.5V absolute max. Bypass with a 1uF input capacitor (CIN) to VSS as close to the pin as practical.
3 VOUT power_out Regulated 5.0V output (±2% tolerance) capable of sourcing up to 1A. Requires a 1uF tantalum or 6.8uF ceramic output capacitor (COUT) to VSS for stability.
