ABSTRACT:
The reliability of the power supply unit which supplies a different voltage to the microcomputer with two or more power supplies is improved. The power supply unit is composed of first regulator2, at least one second regulator4which generates the voltage lower than that of the first regulator2, means for detecting the output voltage of the first regulator2, and means for stopping the second regulator4when the output voltage V2of the first regulator2drops lower than the first fixed voltage.
