Abstract
Provided is a voltage regulator including an overcurrent protection circuit in which an output voltage-output current characteristic exhibits an optimal fold-back characteristic even when an overcurrent state is detected. The overcurrent protection circuit includes a control circuit for generating a current in accordance with an output voltage, and controls a gate of an output transistor with use of a current obtained by subtracting the current from a sense current flowing in accordance with an output current.
