SSP7901P30PR

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

SSP7901P30PR 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 regulator; the datasheet gives no separate electrical limit for this pin, and the output voltage absolute maximum rating is referenced to Vss (Vss-0.3V minimum).
2 Vin power_in Regulator input supply pin, rated to a 40V absolute maximum (-0.3V to 40V), with a recommended input voltage range of -0.3V to 36V and an electrical-characteristics input voltage range of 2.2V to 40V.
3 Vout power_out Regulated output pin, which must stay within Vss-0.3V to VIN+0.3V and is limited to a maximum output current of 300mA.
