Abstract

PURPOSE: To maintain the effective value of the output voltage constant even when the input voltage increased, by switching the current generating circuit or the constant current circuit for charging the capacitor by means of the output from the voltage comparator.
CONSTITUTION: The output terminal of the current generating circuit 1 or the constant current circuit 2 is connected to the capacitor 4 in accordance with the function of the switching circuit 3. The terminal voltage of the sapacitor 4 is provided to the voltage comparator 5. The output from the voltage compartor 5 having the hysteresis characteristic is provided to the switching circuit 3. The output voltage from the voltage comparator 5 is supplied to the load circuit.
