PROBLEM TO BE SOLVED: To solve such a problem that an output voltage is unsettled when an input voltage rises slowly from a low level at the time of starting or operation due to the erroneous operation of a control circuit caused by a detection delay time of a UVLO operating on a high voltage out of two UVLOs having different operating voltage ranges even if a release voltage of a UVLO operating on a low voltage is exceeded. SOLUTION: The unsettlement of an output voltage is prevented even when an input voltage is low by setting the release delay time of a UVLO operating on a low voltage longer than the detection delay time of a UVLO operating on a high voltage.
