Claim:
1. A regulator configured to provide a load current at an output voltage in dependence of an input voltage; wherein the regulator comprises a core regulator configured to provide a core current at a core output voltage in dependence of the input voltage; current sensing means configured to provide an indication of the core current; wherein the output voltage is dependent on the core output voltage and on a voltage drop at the current sensing means; a current source configured to provide an auxiliary current based on the indication of the core current; wherein the load current is dependent on the core current and on the auxiliary current; and offset circuitry configured to offset a core input voltage to the core regulator relative to the input voltage, such that the output voltage is proportional to the input voltage, thereby compensating the voltage drop at the current sensing means.
