Abstract:
A voltage supply circuit driven by a power supply voltage for supplying an output voltage, comprising:reference voltage generation means driven by said power supply voltage for generating a reference voltage;driver means receiving said power supply voltage and supplying said output voltage;dividing means including first and second resistor means for dividing the output voltage supplied by said driver means and supplying a divided output voltage, said first and second resistor means having resistance values of different temperature coefficients; andcomparison means for comparing said divided output voltage supplied by said dividing means and said reference voltage generated by said reference voltage generation means and controlling said driver means based on the difference between said divided output voltage and said reference voltage;wherein said first resistor means is connected between a node receiving said output voltage and an output node outputting said divided output voltage obtained by dividing,said second resistor means is connected between said output node and a prescribed potential,the resistance value of said first resistor means has a first temperature coefficient, and the resistance value of said second resistor means has a second temperature coefficient smaller than said first temperature coefficient, andsaid first temperature coefficient is positive and said second temperature coefficient is negative.
