Abstract

See full text

A regulator includes a driving circuit, an amplifying circuit and an overvoltage protection circuit. The driving circuit is configured to receive an input voltage and provide an output voltage through an output terminal. The amplifying circuit is configured to control the driving circuit according to the output voltage. The overvoltage protection circuit is configured to conduct a first current from the output terminal of the overprotection circuit to a ground terminal. When the overvoltage protection circuit detects that a voltage level of a node coupled to the driving circuit is increased, the overvoltage protection circuit conducts a second current from the output terminal of the overprotection circuit to the ground terminal to lower the output voltage, in which the second current is larger than the first current.
