INTEGRATED CIRCUIT WITH LOW ENERGY CONSUMPTION IN A POWER SAVING MODE

摘要

The invention relates to an integrated circuit comprising at least one voltage regulator, which is connected between a supply potential terminal and a reference potential terminal. The integrated circuit also has at least one useful circuit, which contains a memory and/or logic unit, whose supply potential input is coupled to the output of the voltage regulator. According to the invention, the voltage regulator can be switched off by a first switching device in a power saving mode. The supply potential input of the useful circuit is then connected to the supply potential terminal via a diode circuit.
