Note) All the characteristic values are measured with a 0.33

µF-capacitor connected the input pin and 22µF-capacitor connected to the output pin.

Measurements are made by using a plus (tw

≤10ms, duty cycle≤5%) in all cases but noise voltage and the ripple rejection ratio.

Not designed for radiation resistance.
