SE8233X2-HF

Seaward Elec · Linear Voltage Regulators (LDO) · SOT-23

SE8233X2-HF from Seaward Elec, in a SOT-23. 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 datasheet gives no further limits.
2 VOUT power_out Output pin; fixed 3.0V, 3.3V or 5V output with ±1% accuracy, 100mA minimum output current capability, and absolute maximum 15V to GND.
3 VIN power_in Input pin; operates from VOUT+1V up to 24V recommended maximum (30V absolute maximum), with UVLO at 1.8V.
