SE8533K1-HF

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).
