SL7603P28PR from Slkor SLKORMICRO Elec, 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, pin 1 at left in the SOT89-3 top view. |
| 2 | VIN | power_in | Input supply pin, input voltage range 3.5V to 15V (absolute maximum -0.3V to 18V). |
| 3 | VOUT | power_out | Regulated 2.8V output (±2% tolerance) for the SL7603P28 with up to 500mA output current. |
