Abstract
A low-dropout (LDO) regulator having an analog low-dropout (ALDO) regulating circuit assisted by a digital low-dropout (DLDO) regulating circuit is shown. The DLDO regulating circuit is coupled to the ALDO regulating circuit, and senses operating information that shows if the ALDO regulating circuit is within its operating region. The DLDO regulating circuit assists the ALDO regulating circuit based on the operating information of the ALDO regulating circuit instead of an output voltage at the output terminal of the LDO regulator.
