Abstract
When a low operation voltage device is idle and a voltage of an external power supply is larger than a predetermined voltage, a transistor with a high threshold voltage is turned on to provide electric power to the low operation voltage device. When the low operation voltage device is operating and the voltage of the external power supply is not larger than the predetermined voltage, a transistor with a low threshold voltage is turned on to provide electric power to the low operation voltage device.
