Abstract

A low dropout (LDO) voltage regulator having more than one LDO modules, each LDO module having a frequency response adapted to a certain range of output frequency. The LDO voltage regulator can provide a gain over a broad range of operating frequency by combining output current from each LDO module and providing the combined current at an output of the LDO voltage regulator. The LDO voltage regulator further comprises a load monitor coupled to the LDO modules for disabling some of the LDO modules to reduce power consumption of the LDO voltage regulator.
