Abstract
A switching regulator includes a comparator, an on-time control circuit, an R-S flip-flop circuit, and a timer circuit that outputs a count-up signal, where the comparator switches an operation current to a low current consumption mode in response to the count-up signal so as to reduce the operation current in a light load operating mode.
