Patent ID: 6922099

Claim:
Circuitry comprising: a voltage regulator comprising a first stage and a second stage, wherein an output of said first stage is coupled to an input of said second stage, wherein current of said second stage is minored through a current path to a current mirror driver, said current mirror driver adapted to perform a first Class AB action comprising at least one of sourcing and sinking current from a voltage supply VPP, wherein an output of said current mirror driver is connected to an output of said voltage regulator; a first circuit connected to said current path and adapted to sample current in said current path, wherein during steady state current in said current path, said first circuit provides negligible current to the output of said voltage regulator, and during transient current conditions, said first circuit performs a second Class AB action complementary to said first Class AB action comprising at least one of sinking and sourcing current from the voltage supply VPP; and wherein said first and second stages both operate from a voltage supply VDD, which is at a lower voltage than VPP.
