Abstract
A voltage regulator and a gate control circuit for an aid transistor coupled to assist a pass element for the voltage regulator during line transients having a given slope are disclosed. The gate control circuit includes a first circuit coupled to receive an output voltage of the voltage regulator on a first node and to provide a gate control voltage that mirrors the output voltage on a second node. A low pass filter is coupled to receive the gate control voltage and to provide a filtered gate control voltage to the gate of the aid transistor.
