Low-dropout regulator

A low-dropout regulator, comprising:

• an analog low-dropout regulating circuit;
• and
• a digital low-dropout regulating circuit, assisting the analog low-dropout regulating circuit;
• wherein:
• the digital low-dropout regulating circuit is coupled to the analog low-dropout regulating circuit, and the digital low-dropout regulating circuit senses operating information that shows if the analog low-dropout regulating circuit is within its operating region;
• and
• the digital low-dropout regulating circuit assists the analog low-dropout regulating circuit based on the operating information of the analog low-dropout regulating circuit instead of an output voltage at an output terminal of the low-dropout regulator.
