Abstract

A method of regulating a low-dropout (LDO) regulator is provided. The method includes: generating a feedback voltage by receiving a feedback from an output node of the LDO regulator, generating a control signal to drive a pass element by receiving the feedback voltage and a reference voltage, detecting a voltage at a first node and controlling a switching operation of a first switch according to a detection result by a detection circuit. When the LDO regulator is operating in an active mode, the first switch is turned on to connect the first node and a control terminal of the pass element and when the LDO regulator is operating in a standby mode, the first switch is turned off to disconnect the first node from the control terminal of the pass element. A low-dropout (LDO) regulator is also provided.
