Abstract

The present invention relates to a circuit arrangement to monitor a regulated output voltage in an automotive vehicle, wherein the regulated output voltage is monitored as to whether defined threshold values have been exceeded and/or have fallen short of, wherein the circuit element for regulating the output voltage and the circuit element to monitor whether threshold values have been exceeded or have fallen short of are integrated in one chip, wherein the adjustment of the output voltage is effected by way of a first reference voltage, and wherein monitoring of the threshold values as to whether they have been exceeded or have fallen short of is conducted by way of a second reference voltage.
