ABSTRACT:
An electronic device with a plurality of electronic components, the electronic device includes a microcomputer, a first regulator supplying power required to drive the microcomputer in a first mode of the electronic device, a second regulator supplying power required to drive at least one among the plurality of electric components in a second mode of the electronic device, and a controller controlling the power from the second regulator to be employed as power for driving the microcomputer when the electronic device operates in the second mode. With this configuration, the electronic device, especially in a case of a portable electronic device using a battery, has a longer running time and a life span of a battery is increased.
