PURPOSE: A multi voltage regulator is provided to output stable multi voltage by improving output regulations. CONSTITUTION: An error amplifier(300) amplifies differential voltage of reference voltage and feedback voltage. A first voltage regulator(100) controls a voltage level of a power source input terminal and outputs and outputs voltage to a first output terminal. A second voltage regulator(200) controls the voltage level of the power source input terminal and outputs the voltage to a second output terminal. A voltage detection part(400) detects voltage according to voltages of the first and second output terminals and provides the detected voltage as the feedback voltage.
