Abstract
A constant-voltage generation circuit is provided which creates a constant voltage. The constant-voltage generation circuit may consist of a first voltage creation circuit for creating a reference voltage and a second voltage creation circuit for creating a constant voltage which has a predetermined relationship with the reference voltage. The first voltage creation circuit may consist of a constant-current source for supplying a constant current and a voltage-control transistor through which this constant current flows, for outputting the reference voltage on the basis of a predetermined potential. The constant current is set to a value within the saturated operating region of the voltage-control transistor.
