Abstract
A low-dropout regulator circuit includes a reference circuit, an amplifying circuit, a power switch circuit, a feedback circuit, and a control circuit. The reference circuit is configured to generate a reference voltage. The amplifying circuit is configured to generate an amplifying voltage according to the reference voltage and a feedback voltage. The power switch circuit is configured to receive the amplifying voltage and generate an output voltage at an output terminal according to an input voltage. The feedback circuit is configured to generate the feedback voltage according to the output voltage. The control circuit is configured to control the power switch circuit according to the input voltage and a signal from the reference circuit.
