ABSTRACT:
An apparatus and method for providing dynamic voltage regulation for a system with a fluctuating current demand are disclosed. A first voltage regulator is used for producing regulated output to the system. A control circuit activates a second voltage regulator with faster transient response than the first voltage regulator to help source current when the first voltage regulator is unable to adequately respond to an increase in current demand from the system. The control circuit activates a load element to help sink current at the output of the first voltage regulator when the first voltage regulator is unable to adequately respond to a decrease in current demand from the system.
