Abstract: According to an embodiment, a voltage regulator having an output transistor, a voltage dividing circuit, an error amplifier, a detection circuit and a phase compensation capacitance circuit is provided. The output transistor has one end to which a power supply voltage is supplied, a control terminal to which a control signal is input, and the other end which outputs an output voltage. The voltage dividing circuit is connected between the other end of the output transistor and a first reference voltage. The error amplifier is configured to output the control signal according to the difference between a divided voltage and a second reference voltage. The detection circuit is configured to detect an operation environment. The phase compensation capacitance circuit is configured to adjust a phase compensation capacitance between the other end of the output transistor and an input terminal of the error amplifier, in accordance with the detected operation environment.
