Abstract
A level shift element is connected between a transistor (Tr.sub.5) which is used to determine a threshold level when the input voltage falls and a diode (D.sub.3) is connected between an input terminal and an output control transistor (Tr.sub.2) to discharge the base of the output control transistor. The level shift element comprises a diode connected in the forward direction or a resistor.
