置。[Claims for Utility Model Registration] A power supply voltage Vcc is received from the outside, a reference voltage input 3 and an output voltage feedback input 4 are received, and an abnormal voltage is generated to control the output voltage to be equal to the reference voltage. In the constant voltage power supply device for preventing the above, a resistor 8 having a sufficiently high resistance value compared to the load is provided between the supply line that returns the output voltage and the voltage source having a potential difference larger than the reference voltage. A constant voltage power supply that prevents abnormal voltage from occurring.
