ABSTRACT:
A voltage control unit is provided to continuously monitor a reference output voltage by using a voltage monitoring circuit. When the reference output voltage is lower than a predetermined value, a pair of series transistors are turned ON by a detection output to thereby pull up the reference output voltage to the power supply voltage, and further to pull up the reverse phase input voltage to the reference output voltage. Then, the control is carried out in such a way that the reverse phase input voltage exceeds the normal phase input voltage. As a result, a reference voltage generating circuit is capable of providing a smooth ramp up voltage at power up or during any time the supply voltage is below the predetermined voltage.
