Abstract:
A regulator configured to provide at an output node a load current at an output voltage is described. The regulator comprises a pass transistor for providing the load current at the output node. Furthermore, the regulator comprises feedback means for deriving a feedback voltage from the output voltage at the output node. In addition, the regulator comprises a differential amplifier configured to control the pass transistor in dependence of the feedback voltage and in dependence of a reference voltage. The regulator further comprises compensation means configured to determine a sensed current which is indicative of the load current at the output node. Furthermore, the compensation means are configured to adjust an operation point of the regulator in dependence of the sensed current and in dependence of a value of a track impedance of a conductive track which links the output node to a load.
