A voltage regulator for providing a voltage regulated output to a load comprises a first loop and a second loop. The first loop comprises a first active device coupled to a first pass device and configured to provide a first, relatively high current output to the load. The second loop comprises a second active device coupled to a second pass device and configured to provide a second, relatively low current output to the load. In this manner, when the inventive concept is applied to low drop-out regulators, the provision of two independent loops reduces dramatically the quiescent current provided by the voltage regulator under low load conditions.
