A series voltage regulator circuit includes first and second voltage regulators, a first controller to control an output voltage of the first voltage regulator, and a second controller to control an output voltage of the second voltage regulator. The voltage regulators preferably include internal control loops which rapidly respond to the load variations, however the controllers operate independently from these variations. By isolating the controllers from the load, the controllers are able to maintain the output of the regulators at a constant value. In one embodiment, the voltage regulators are connected in a push-pull configuration for driving the load.
