Abstract
A controller is described with a final stage which provides a defined supply voltage for a downstream electronic circuit and a circuit stage upstream from the final stage for reducing the quiescent current supplied by a voltage source. A significant reduction of the quiescent current is achieved by simple means in that the circuit stage has an electronic switch that can be set to the open or closed state by a target-value signal (SW) supplied by a control circuit.
