Abstract
A regulator to provide an output voltage of a constant level at an output node. In an embodiment, the regulator contains a pass transistor to provide a conductive path between a pair of terminals, with the resistance offered by the path being determined by a control voltage on a third terminal of the pass transistor and the conductive path coupling a first reference potential (e.g., power supply) to the output node. An amplifier generates the control voltage based on a difference of a reference voltage and a voltage proportionate to the output voltage. A control unit turns on a current source when the voltage at the output node is below the desired constant level and turns on a current sink when voltage at said output node is above the constant level, to quickly correct for any variations in the output voltage due to load changes.
