Abstract
A stabilized power-supply circuit comprising an input terminal to be connected to an electric power source, and an output terminal to be connected to a load and an auxiliary power source. An error signal generator is provided to receive a reference voltage at its one input, and a drive circuit is connected to an output of the error signal generator. Further, an output circuit is connected between the input terminal and the output terminal and driven by the drive circuit so as to supply a controlled voltage to the output terminal, and a feedback circuit is connected at its one end to the output terminal and at its other end to the other input of the error signal generator. In this power-supply circuit, there is provided a circuit for monitoring the voltage on the output terminal so as to bring the output circuit in a cut-off condition when the output terminal voltage drops.
