SSP7901P50PR

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

SSP7901P50PR from Shanghai Siproin Microelectronics, in a SOT-89-3L. 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 pin of the SSP7901P package variant, to which the input and output voltages are referenced.
2 Vin power_in Input supply pin with an input voltage range of 2.2V to 40V, where the absolute maximum input voltage is 40V and the recommended maximum is 36V.
3 Vout power_out Regulated output pin that supplies up to 300mA maximum output current, with output voltage accuracy of ±2% at VIN = VOUT+2V and IOUT = 10mA.
