Abstract
The voltage generator includes the NPN transistor that flows a current corresponding to a voltage VOP output from the error detector. Furthermore, there is provided the current mirror circuit which includes two PNP transistors that flow currents which are multiples of the current that the NPN transistor flows. Furthermore, there are provided two resistors for generating a feedback voltage VFBK to the error detector from an output voltage VREG generated based on a current that the current mirror circuit flows.
