SSP7603P33PR 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, leftmost pin in the SOT89-3 top view. |
| 2 | VIN | power_in | Supply input, specified 3.5V to 15V (absolute maximum 18V), with a 1uF input capacitor recommended. |
| 3 | VOUT | power_out | Regulated 3.3V output (±2%) for the SSP7603P33, up to 500mA, with a 1uF tantalum or 6.8uF ceramic output capacitor recommended. |
