A voltage regulator improves its transient adjustment response by amplifying error in its regulation feedback control path, including any droop-related error. Amplifying the error speeds up the voltage regulator's response to load changes and droop control adjustments by exaggerating the feedback error. Thus, in at least one embodiment, a droop control circuit imparts a droop-related offset between an output feedback signal and a reference signal responsive to a droop adjustment signal, and a response-enhancing amplifier circuit amplifies that offset for input to an error sensing circuit of a regulation control circuit. The gain and frequency response of the response-enhancing amplifier circuit may be set as a function one or more regulation stability criteria, and the response-enhancing method may be adapted to a variety of voltage regulator topologies. Such topologies include, but are not limited to, PWM regulators and hysteretic regulators.
