Abstract
A voltage regulator () comprises a first transistor () which couples an input terminal () of the voltage regulator () to an output terminal () of the voltage regulator () and a second transistor (). The first and the second transistors () form a current mirror structure. Further on, the voltage regulator () comprises a control node () which is coupled to the input terminal () of the voltage regulator () via the second transistor () and which is coupled to the output terminal () of the voltage regulator () via a feedback circuit (). Furthermore, the voltage regulator () comprises an amplifier () with an input terminal () which is coupled to the control node () and an output terminal () which is coupled to a control terminal () of the second transistor ().
