Abstract
A voltage regulator includes an output transistor which outputs an output voltage to an output port; a dividing resistor which divides an adjustment voltage input to a voltage adjustment port and outputs a feedback voltage; a first reference voltage circuit which outputs a first reference voltage; an error amplifier circuit which controls a gate voltage of the output transistor based on the first reference voltage and the feedback voltage; and a ground fault protection circuit which, upon monitoring the adjustment voltage and detecting the voltage adjustment port having a ground fault, increases the feedback voltage to the first reference voltage.
