SK7550-1 from Shikues, 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 pin, the common reference for the regulator. |
| 2 | VIN | power_in | Input pin; the general description states the input can be as high as 24V, while the absolute maximum supply voltage is 33V. |
| 3 | VOUT | power_out | Regulated output pin; for SK7550-1 the output is 5.0V (4.850V to 5.150V) and the part can deliver 100mA output current. |
