An electrical current source with a high output resistance has a current determining transistor and a regulating switch. The regulating switch has an amplifier circuit with transistors and a regulating transistor, and allows the electrical supply to have a high output resistance. To enable the electrical supply to be used at even very low operating voltages, a sourcing circuit is provided, which is used for setting a freely selectable minimal decrease in voltage over the supply. The sourcing circuit has one or more transistors and influences the voltage at the current determining transistor. The output resistance of the electrical source can be further improved by utilizing a correcting circuit that has resistors.
