Abstract
A semiconductor integrate circuit device includes: an output transistor connected between a voltage input terminal to which a DC voltage is input and a voltage output terminal; a control circuit that controls on/off of the output transistor; a proportional current generation circuit capable of generating a current proportionally smaller than a current flowing through the output transistor; an overcurrent detection circuit capable of detecting an overcurrent state of an output current by determining whether a current flowing through the output transistor is equal to or greater than a first predetermined current value, based on the current generated by the proportional current generation circuit; and a retry circuit that generates and outputs a signal for intermittently turning off the output transistor in response to the overcurrent detection circuit detecting the overcurrent state.
