Provided is a voltage regulator including a leakage current sink circuit capable of suppressing an influence of a leakage current of an output transistor at high temperature, and reducing power consumption of the voltage regulator at normal temperature. The voltage regulator includes: a reference voltage circuit configured to output a reference voltage; an output transistor configured to output an output voltage; a voltage divider circuit configured to divide the output voltage to output a feedback voltage; an error amplifier circuit configured to amplify a difference between the reference voltage and the feedback voltage, and output the amplified difference to control a gate of the output transistor; and a leakage current sink circuit connected to an output terminal and configured to be prevented from operating at normal temperature, and suppress an influence of a leakage current from the output transistor only at high temperature.
