ABSTRACT:
A low-power charge pump regulator is provided. The low-power charge pump regulator may periodically turn off charge pumping portions of the charge pump circuitry to reduce power consumption. The charge pumping portions of the charge pump circuitry may then be turned on when they are needed to maintain the output of the charge pump regulator. In some embodiments, where the leakage off the voltage regulator output is small, the charge pumping portions of the charge pump circuitry may only need to be turned on for brief periods of time.
