Patent ID: 8022681

Claim:
A voltage regulator circuit adapted to supply N regulated output voltages, the voltage regulator circuit comprising: a digital control block operative to receive a first reference voltage and selectively receive one of N feedback voltages; and N voltage regulation channels each associated with one of the N feedback voltages, each voltage regulation channel comprising: a sample-and-hold block responsive to an output of said digital control block; an amplifier responsive to an output of an associated sample-and-hold block; and a transistor having a first terminal responsive to an output of an associated amplifier, a second terminal receiving one of N input voltages to be regulated, and a third terminal supplying one of N regulated output voltages, wherein the output voltage of the digital control block causes a difference between the associated received feedback voltage and the first reference voltage to be less than a predefined value, wherein said regulated output voltages are responsive to the reference voltage.
