Abstract
Disclosed herein is a switching regulator with a soft start circuit for suppressing an in-rush current. The switching regulator includes a peak detector configured to receive a clock signal and detect a peak voltage of the clock signal, a comparator configured to generate a soft start signal for controlling a soft start of the switching regulator based on a result of comparing a level of the peak voltage of the clock signal to a preset reference voltage level, a counter configured to switch a state of the soft start signal at a time point when a preset soft start time arrives, and a ramp voltage generation unit configured to generate a ramp voltage by adjusting a resistance of a variable resistor based on the soft start signal.
