Abstract

Circuit, method for operating a circuit, and use, having a voltage regulator, which has a regulator output for providing a supply voltage, which for the supply can be connected to at least one first digital subcircuit via a first switch and to a second digital subcircuit via a second switch, wherein the voltage regulator is formed to output a first status signal dependent on the supply voltage, and to turn on the first switch by the first status signal is connected to a first control input of the first switch, and the first switch is formed to output a second status signal dependent on its switching state, and to turn on the second switch by the second status signal is connected to a second control input of the second switch.
