Abstract:
A voltage regulator which provides an output current at an output voltage at an output node of the voltage regulator, based on an input voltage at an input node of the voltage regulator is described. The voltage regulator has an output amplification stage for deriving the output current at the output node from the input voltage at the input node in dependence of a drive voltage. Furthermore, the voltage regulator has a differential amplification stage to determine the drive voltage in dependence of the output voltage and in dependence of a reference voltage. In addition, the voltage regulator has an adaption unit to determine a capacitance indication of a capacitor value of an output capacitor coupled to the output node of the voltage regulator. The adaption unit also adapts the differential amplification stage in dependence of the capacitance indication.
