Abstract
A source-grounded amplifier circuit supplied with a signal of an error amplifier circuit, and an output transistor supplied with a control voltage of the source-grounded amplifier circuit are provided. The source-grounded amplifier circuit has, in a signal path, a current limiting circuit including a cascode circuit controlled by a voltage having a positive temperature coefficient. A voltage regulator capable of reducing a dropout voltage of an output voltage without exceeding a gate breakdown voltage of the output transistor is provided.
