Abstract

PURPOSE: To prevent the deterioration of output signals due to the variance of the respective regulator circuits by changing the pulse width of the output signal through the pulse width modulator, in accordance with the result for comparing the reference voltage or voltage with the regulator output signal.
CONSTITUTION: In the master regulator 1a, and the slave regulator 1b, respectively, the voltage comparators 100a, 100b, a current comparators 101a, 101b and a pulse modulators 102a, 102b are provided. The output voltage V0 from the power circuits 2a, 2b is compared with the reference upper limit voltage VHREF in the circuits 100a, 100b, and the output signal corresponding to the potential difference with respect to the voltage VHREF is outputted. In the circuits 101a, 101b, load current detected in the current detecting circuit in the power circuits 2a, 2b is compared with the reference current value IREF. When the load current exceeds the current value IREF, the output signal corresponding to the exceeded current amount is generated. Then, in accordance with the output of the circuits 100a, 100b and 101a, 101b, the clock pulse width from the oscillator 5 is variably controlled and added to the modulators 102a, 102b.
