ABSTRACT:
An integrated circuit includes a voltage regulator for generating an internal supply voltage. The voltage regulator has one input for applying an actual value and one input for applying a reference voltage as a desired value. The actual value is generated through the use of a first voltage divider from the internal supply voltage. A sensitivity of the voltage regulator is dependent on a resistance of at least one resistor element of the first voltage divider. A second voltage divider, which is connected parallel to the first voltage divider, has the same voltage divider ratio as the first voltage divider and is activatable and deactivatable by at least one switch element.
