Abstract: PURPOSE:To eliminate completely the variation conmponent of the output voltage with the correction given at the reference voltage side, by adding the related voltage obtained from a load current to the reference voltage component of an output error amplifier for stabilization of output voltage. CONSTITUTION:The change of a load current is detected by a detecting circuit 8 i in the form of a voltage change and amplified by a unity amplifier 7 to be supplied to a reverse input part 62 of an operational amplifier 6. While the reference voltage 5 s supplied to the non-reverse input part 61 of the amplifier 6. The reference voltage having a change related to a load current is supplied to a reverse input part 41 of an output error amplifier 4. While the voltage related to the output voltage V is applied to a non-reverse input part 42 of the amplifier 4. Now if the load current increases, the output voltage of the amplifier 7 is reduced by the detection voltage given from the circuit 8. Then the output of the amplifier 6 rises up and the voltage of the part 41 of the amplifier 4 is also increased. Thus the output of the amplifier 4 is reduced. In other words, the rise of the voltage of a stabilized circuit is compensated with the rise of the voltage of the reverse input part due to the increase of the load current.
