ABSTRACT:
A comparator compares a control voltage obtained by amplifying the difference between an output voltage of a DC voltage outputting circuit and a reference voltage, with the voltage between both ends of a sense resistor. The result of this comparison is input to the reset terminal "R" of a flip-flop circuit as a reset signal. For example, if a light load is connected to the DC voltage outputting circuit, the control voltage to be output to the comparators via an amplifier will drop and the output voltage of the DC outputting circuit will rise. Therefore, a threshold voltage is provided to another comparator to which the control voltage is input, and a set pulse signal is not output to the set terminal "S" of the flip-flop circuit if the control voltage is not equal to or higher than the threshold voltage. As a result, the average value of the control voltage can be raised by the value of the threshold voltage, and the voltage rising of the DC voltage outputting circuit can be suppressed in comparison with the conventional system, thereby improving a load regulation.
