A circuit and method for operating a circuit is provided that includes a circuit section that has a number of memory elements, a first voltage regulator that can be connected or is connected to the circuit section in order to operate the circuit section, a second voltage regulator that can be connected or is connected to the circuit section in order to preserve an information item stored in the memory elements, a switching device that is connected to the circuit section and is designed to deactivate and activate inputs of the circuit section. The circuit being configured to control a deactivation and activation of the first voltage regulator and the deactivation and activation of the inputs of the circuit section.
A circuit comprising:
A method for operating a circuit, the method comprising:
Use of a first voltage regulator of a circuit, which provides a supply voltage and an operating current for a circuit section for an operating mode and use of a second voltage regulator of a circuit, which provides a standby voltage and a standby current for the circuit section for a sleep mode, wherein the second voltage regulator consumes less current than the first voltage regulator, and wherein the first voltage regulator is activated and deactivated via the circuit section.
