Abstract
A digital low-dropout regulator (DLDO) and a control method thereof are provided. The DLDO includes a power switch circuit, an error detector and a control circuit, wherein the control circuit is coupled to the power switch circuit and the error detector. The power switch circuit is configured to receive an input voltage to generate an output voltage, wherein a voltage difference between the input voltage and the output voltage is controlled by a switch control code. The error detector is configured to generate an error code according to an error between the output voltage and a target voltage. The control circuit is configured to determine a compensation amount according to the switch control code and the error code, and update the switch control code according to the compensation amount, in order to make the output voltage approach the target voltage.
