Abstract: A voltage regulator, having a control element, having a current feedback circuit, having a negative voltage feedback circuit, having a component for switching between a first mode as a switching regulator and a second mode as a linear regulator and for generating a digital control signal for triggering the control element in the first mode as a switching regulator based on a sum variable, and for generating a linear control signal for triggering the control element in the second mode as a linear regulator based on the sum variable, whereby in the first mode as a switching regulator and in the second mode as a linear regulator, a first output of the current feedback circuit and a second output of the negative voltage feedback circuit are coupled to form the sum variable.
