Abstract
A voltage regulator circuit includes: a first pulse generator configured to output a pulse whose level remains unchanged when an input signal of a first circuit is in a first period, and whose level changes from a second level to a first level when an edge of the input signal of the first circuit is detected after the first period; a second pulse generator configured to output a pulse from a time that the pulse output by the first pulse generator becomes the first level until a second period elapses; a first field-effect transistor having a source connected to a power supply potential node, and a drain connected to a power supply potential terminal of the first circuit; and a first switch configured to cause a potential at a gate of the first field-effect transistor to be a first potential.
