Classification: CPC G  H | IPC G  H

Claim 0:
1. A regulating circuit comprising:
a first direct current-direct current (DC-DC) converter configured to generate a first supply voltage, apply the first supply voltage to a first node in a first mode via a first switch, and apply the first supply voltage to a second node in a second mode via a second switch;
a second DC-DC converter configured to provide a second supply voltage to the second node in the first mode via a fourth switch and provide the second supply voltage to a third node in the second mode via a fifth switch;
a first low drop output (LDO) regulator connected to the first node and is configured to receive the first supply voltage from the first DC-DC converter via the first switch, the first LDO regulator configured to provide an output voltage to an output node by regulating the first supply voltage; and
a second LDO regulator connected to the first node, the second LDO regulator configured to provide an auxiliary current to the first node when the first DC-DC converter does not apply the first supply voltage to the first node via the first switch and supplies the first supply voltage to the second node via the second switch.
