SSP7603P50PR 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 pin (Vss) of the regulator, left-most pin in the SOT89-3 top view. |
| 2 | VIN | power_in | Input supply pin, operating input voltage 3.5V to 15V (absolute maximum supply 18V). |
| 3 | VOUT | power_out | Regulated 5.0V output (±2%) delivering up to 500mA with built-in current limiter, with recommended COUT of 1uF tantalum or 6.8uF ceramic. |
