Abstract

Provided is a low voltage and compact digital control regulator that achieves enhanced stability and reduced variations in ripple voltage and droop characteristics. The digital control regulator includes a first A/D converter configured to generate a first digital signal according to a differential voltage between an output voltage and a first reference voltage, an output stage circuit configured to generate the output voltage, a replica circuit having the same circuit configuration as the output stage circuit and configured to output a replica voltage related to the output voltage, a second A/D converter configured to generate a second digital signal according to a differential voltage between the replica voltage and a second reference voltage, and a control circuit configured to generate a control signal for controlling a gain of the output stage circuit, according to the first digital signal and the second digital signal.
