摘要
A low-dropout regulator comprises an analog-to-digital converter that converts a feedback analog voltage signal into a digital signal, a phase synthesizing unit that generates a first control signal having a pulse width corresponding to error information in the digital signal by performing phase synthesis according to clock skew control, a charge pump circuit that selects a charge loop or a discharge loop based on polarity information in the digital signal, and generates an output control voltage according to current that flows during a period corresponding to the pulse width of the first control signal in the selected loop, and an output circuit that generates an output voltage based on an input voltage and the output control voltage, and generates the feedback analog voltage signal based on the output voltage.
