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. |
