Abstract
Provided is an switching regulator including: an error amplification circuit configured to output a first error voltage based on an output voltage and a first reference voltage; a PFM comparison circuit configured to compare the first error voltage with a second reference voltage to output a comparison result signal; an oscillation circuit configured to output a clock signal, and to stop output of the clock signal depending on the comparison result signal; a frequency characteristics separation circuit to which the first error voltage is provided, and from which a second error voltage is supplied; a phase compensation circuit connected to the frequency characteristics separation circuit; and a PWM conversion circuit configured to turn the switching element on and off at a desired pulse width, based on the second error voltage and on the output from the oscillation circuit.
