SSP7985P30PR

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

SSP7985P30PR from Shanghai Siproin Microelectronics, in a SOT-89. 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, connected to the bottom of the R1 feedback divider and the error amplifier reference.
2 VIN power_in Input supply pin, operating range 5V to 60V (absolute maximum 80V relative to GND).
3 VOUT power_out Regulated 3.0V output (SSP7985P30), up to 150mA with 250mA current limit and ±2% accuracy, with 10µF output capacitor specified.
