Abstract
A voltage regulator includes a differential amplifier circuit that controls an output transistor, and a phase compensation circuit. The phase compensation circuit includes: a first transistor having a drain connected to an output port of the differential amplifier circuit, and having a drain-source current with a negative temperature characteristic; a second transistor having a drain connected to a gate of the first transistor, having a gate connected to the gate of the first transistor via a resistor, and having a drain-source current with a negative temperature characteristic; and a current mirror circuit that includes a voltage detection transistor for detecting a voltage input to the gate of the output transistor, and that supplies a current with a positive temperature characteristic in response to a current flowing in the voltage detection transistor.
