SSP7603P36PR from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 (Vss) pin of the regulator, leftmost pin in the SOT89-3 top view. |
| 2 | VIN | power_in | Input supply pin; input voltage range is 3.5V to 15V (absolute maximum supply voltage 18V). |
| 3 | VOUT | power_out | Regulated 3.6V output pin (±2% tolerance) delivering up to 500mA with a built-in current limiter. |
