SE8530K2-HF from Seaward 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 of the SOT89 (insulating-glue) package, pin order G-I-O. |
| 2 | VIN | power_in | Power supply input, operating from VOUT+1V up to 35V (absolute maximum 40V), with a 1μF ceramic capacitor to GND placed close to the pin. |
| 3 | VOUT | power_out | Regulated output voltage (3.0V for the 30 version, 200mA minimum output current), with a recommended 10μF ceramic output capacitor (1μF minimum) to GND. |
