Abstract
A semiconductor integrated circuit includes a first regulator configured to output a first output voltage at a predetermined level from a first output terminal, a second regulator configured to output a second output voltage at the predetermined level from a second output terminal connected to the first output terminal, and a control circuit. The control circuit is configured to turn on the second regulator and then turn off the first regulator such that the first and second regulators both remain on for a certain period of time when a regulator to be used is switched from the first regulator to the second regulator, and during the certain period of time, cause the second output voltage of the second regulator to be increased to a level higher than the predetermined level.
