A constant voltage source consists of a circuit along with an equipped amplifier for supplying an output voltage to a load. In accumulation there is a criticism circuit for feeding backside the output voltage to the prepared amplifier. They also have a recompense circuit along with a next resistor, a second inductance unit and a second bypass capacitor, one finish of each one of the second resistor, the second inductance unit and the second bypass capacitor being connected to all other.
