Abstract
A low dropout (LDO) regulator system is provided. The LDO regulator system includes a first amplifier circuit, a second amplifier circuit, and a switch circuit. The first amplifier circuit has a first input coupled to receive a reference voltage and an output. The second amplifier circuit has a first input coupled to the output of the first amplifier and is configured to provide a predetermined voltage at a first output. The switch circuit is coupled between the first output of the second amplifier circuit and a second input of the first amplifier circuit and is configured to cause an open circuit in a first feedback path from the first output of the second amplifier circuit to the second input of the first amplifier circuit based on a control signal.
