Abstract
A switching regulator is disclosed. In the switching regulator, when a power source voltage is lowered to a first predetermined value due to an overcurrent, a voltage boost operation is temporarily stopped, and a delay timer of a delay circuit is not reset. When the overcurrent is detected again due to a rise of the power source voltage after temporarily stopping the voltage boost operation, the delay timer of the delay circuit continues to count the delay period. The voltage boost operation is completely stopped by receiving a signal output from the delay circuit when the delay timer completes the counting after passing a predetermined delay period.
