摘要
A circuit and a method for supplying a regulated voltage to a target circuit characterized by fast changes in current loading are described. A voltage regulator supplies the regulated voltage to an output node. The voltage regulator has a transistor having a gate, a first terminal connected to a power supply terminal, and a second terminal connected to the output node of the voltage regulator. A voltage transition generator is capacitively coupled to the gate of the transistor to increase or decrease its driving power upon occurrence of an event in the target circuit indicating a change in current loading. The change in current loading can have an expected magnitude, and the voltage transition can have a magnitude that is a function of an expected magnitude of the increase or decrease in current loading.
