Abstract

A device includes a voltage regulator circuit, a power switch circuit, and a control circuit. The voltage regulator circuit generates an output voltage at an output terminal. The power switch circuit is coupled to the voltage regulator circuit. The control circuit receives a first control signal and generates a second control signal that includes a first portion gradually declining between a first time and a second time later than the first time. When the voltage regulator circuit is turned off and a logic state of the first control signal changes at the first time, the power switch circuit is turned on at the second time, in response to the second control signal, to adjust the output voltage.
