The voltage regulator provides a source voltage fluctuation detecting circuit for detecting a fluctuation in source voltage in a comparison circuit for comparing the source voltage with output voltage so that when the source voltage rises sharply, the current through constant current circuits for limiting the consumption current of the comparison circuit will be increased to improve the response characteristics.

Abstract: A voltage regulator has a phase compensation circuit which changes consumption current according to load current thereby to reduce consumption current. The phase compensation circuit includes: a first transistor having a drain connected to an output terminal of an error amplifier circuit; a second transistor having a drain connected to a gate of the first transistor and a gate connected to the gate of the first transistor; a current mirror circuit connected to the output terminal of the error amplifier circuit, a drain of the first transistor, and the drain of the second transistor; and a capacitor connected between the gate of the second transistor and a drain of an output transistor. Thereby, current consumed by the phase compensation circuit can be changed according to the load current, resulting in that the voltage regulator consumes less current.
