SSP7603P50PR

Shanghai Siproin Microelectronics · Linear Voltage Regulators (LDO) · SOT-89-3

SSP7603P50PR 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 pin (Vss) of the regulator, left-most pin in the SOT89-3 top view.
2 VIN power_in Input supply pin, operating input voltage 3.5V to 15V (absolute maximum supply 18V).
3 VOUT power_out Regulated 5.0V output (±2%) delivering up to 500mA with built-in current limiter, with recommended COUT of 1uF tantalum or 6.8uF ceramic.
