ABSTRACT:
A circuit for voltage regulation is provided. The circuit includes a variable output voltage regulator and an output capacitor circuit. The output capacitor circuit includes at least two output capacitors and at least one switch. The variable output voltage regulator is capable of providing a regulated DC output voltage at two or more different voltage levels. When the output voltage is changed to a lower output voltage level, one of the output capacitors in the output capacitor circuit is switched out of the circuit to conserve the charge stored on it. When the output voltage returns to the higher output voltage level, the output capacitor that was switched out is switched back in.
