ABSTRACT:
An alterable DC power supply circuit includes a regulator, a resistor, and an adjustable load resistance. The regulator includes a voltage input pin, a voltage output pin, and an adjusting pin. The resistor is coupled between the voltage output pin and the adjusting pin. The adjustable load resistance is coupled between the adjusting pin and ground. The output voltage of the alterable DC power supply is adjustable by adjusting the adjustable load resistance. Using this alterable DC power supply to test the voltage stability of a chipset improves testing efficiency.
