Abstract: A voltage regulating circuit including a conversion circuit configured to convert a voltage pulse sequence into a filtered analog voltage, wherein the voltage pulse sequence represents a predefined operating limiting voltage, and a regulator configured to receive the filtered analog voltage as regulation variable and to regulate an output voltage of the voltage regulating circuit to a predefined desired voltage.

Abstract: Various embodiments provide a voltage regulator. The voltage regulator includes a supply voltage input to apply an input supply voltage, a supply voltage output to output an output supply voltage, and a first field effect transistor and a second field effect transistor, which are connected in series between the voltage supply input and the voltage supply output. The first field effect transistor has a higher operating voltage than the second field effect transistor. The voltage regulator further includes a regulator designed to set the gate voltage of the first field effect transistor and the gate voltage of the second field effect transistor to regulate the output supply voltage on the basis of a reference voltage.
