Abstract:
An internal power-source potential supply circuit for supplying an internal power-source potential to a predetermined load, comprising:internal power-source potential applying means having a first end receiving an external power-source potential, and a second end for applying the internal power-source potential to said predetermined load in response to a control signal; a resistor element having a first end connected to the second end of said internal power-source potential applying means; current supply means for supplying a predetermined current flowing between a second end of said resistor element and a fixed potential; and a comparator circuit for receiving a divided internal power-source potential from the second end of said resistor element and a reference potential to output said control signal on the basis of a comparison result between the divided internal power-source potential and reference potential, wherein a value of said predetermined current is independent of fluctuation in said reference potential.
