Abstract
Provided is a switching regulator configured to suppress noise coupling, which may occur when a comparator is switched between a normal current operation and a low current consumption operation, to thereby operate stably. The switching regulator has a configuration in which switches are connected to input terminals of the comparator, and a feedback resistor having a large resistance value is disconnected from the input terminal of the comparator when switching is performed between the normal current operation and the low current consumption operation.
