Seaward Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
SE8533K1-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 regulator (SOT89 insulating-adhesive variant, G-I-O pinout). |
| 2 | VIN | power_in | Power supply input operating from VOUT+1V up to 35V (40V absolute maximum), with a 1μF ceramic capacitor to GND placed close to the pin. |
| 3 | VOUT | power_out | Regulated output voltage (3.3V for this SE8533 version, ±1% accuracy) supplying at least 200mA, with a recommended 10μF ceramic capacitor (1μF minimum). |
