SSP7603P36PR

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

SSP7603P36PR 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 (Vss) pin of the regulator, leftmost pin in the SOT89-3 top view.
2 VIN power_in Input supply pin; input voltage range is 3.5V to 15V (absolute maximum supply voltage 18V).
3 VOUT power_out Regulated 3.6V output pin (±2% tolerance) delivering up to 500mA with a built-in current limiter.
