Abstract
A power management system comprises an input power detector configured to generate a first enablement signal by detecting whether a first voltage is supplied; a first output stage connected to the input power detector and configured to receive and regulate the first voltage upon receiving the first enablement signal; an error operational amplifier is connected to the first output stage, a first input port of the error operational amplifier is configured to receive a first reference voltage, a second input port of the error operational amplifier is connected to a connection point of a first resistor and a second resistor, the first resistor is connected to the first output stage, the second resistor is connected to ground, and a system output port is located at the connection of the output port of the first output stage and the first resistor, to drive a load.
