Circuit device, switching regulator, and electronic apparatus

A circuit device comprising:

• a comparator that includes an input terminal and an output terminal, and outputs an output signal that is activated when a potential of the input terminal is lower than a determination level from the output terminal;
• a switch circuit that is electrically connected between an output node connected to a switching element that enters a conduction state or a non-conduction state according to a drive signal and the input terminal of the comparator, and is in a non-conduction state when the switching element is in a conduction state;
• and
• a control circuit that controls a level of the drive signal such that the switching element will not enter a conduction state again based on at least one of length of a period during which and the number of times the output signal of the comparator is activated after the switching element has transitioned from a conduction state to a non-conduction state.
