Claim 12:
13. A method of operating a regulating circuit for supplying an output voltage to an output node by regulating a voltage of a first node, the method comprising:
switching an output end of a first direct current-direct current (DC-DC) converter from the first node to a second node;
applying an auxiliary current to the first node by a second low drop output (LDO) regulator directly connected to the first node in response to a disconnection between the output end of the first DC-DC converter and the first node and a connection between the output end of the first DC-DC converter and the second node;
supplying the output voltage by regulating the voltage of the first node by a first LDO regulator;
switching an output end of a second DC-DC converter from a third node to the second node; and
switching the output end of the first DC-DC converter from the second node to the first node.
