SSP7901P40PR

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

SSP7901P40PR 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 for the regulator; the datasheet gives no electrical limit for this pin beyond its role as the common return.
2 Vin power_in Regulator input supply; absolute maximum is 40 V (VIN -0.3 V to 40 V), recommended operating maximum is 36 V, and the minimum input is 2.2 V.
3 Vout power_out Regulated output (positive fixed voltage); maximum output current is 300 mA, and output voltage must stay within VIN+0.3 V per the absolute maximum ratings.
