Patent ID: 7126316

Claim:
A voltage regulator comprising: an input stage having a first input, a second input, and an output; a reference voltage circuit coupled to said first input; an output stage coupled to said second input; and a gain stage comprising a buffer device and a drive circuit, said buffer device coupled to said output of said input stage and said drive circuit, said drive circuit coupled to said output stage, said drive circuit comprising: a first transistor coupled to said output stage; a base current translation circuit; and a current divide circuit coupled to the first transistor and to said base current translation circuit, wherein said current divide circuit is operable to deliver a portion of a first current of said first transistor to said base current translation circuit; and wherein said base current translation circuit is operable to deliver to the base of said first transistor a second current; wherein said buffer device is operable to provide isolation between said input stage and said drive circuit.
