  • OUTPUT DRIVER CIRCUITS FOR VOLTAGE REGULATORS
    Publication number: 20110115452
    Abstract: An output driver circuit having an input stage and an output stage, wherein the output stage and the input stage are configured to function as (1) a low-frequency voltage follower and (2) a high-frequency feedback loop for the output driver circuit. In operation, the low-frequency follower and the high-frequency feedback loop may precisely regulate the output voltage of the output driver circuit when large load transients occur. A compact charge pump may be used to supply additional voltage required to operate a current mirror of the output driver circuit.
