Abstract:
A regulator applied to regulate a first reference voltage on an output terminal, the regulator includes: a sensing circuit, arranged to sense a variation of the first reference voltage on the output terminal to generate a sensing signal; and a gain stage, arranged to provide an adjusting current to the output terminal in response to the sensing signal for reducing the variation of the first reference voltage, and the gain stage is coupled in parallel to a loading circuit powered by the first reference voltage.
