Abstract: A method of recovering a voltage drop at an output terminal of a voltage compensation circuit connected to a load including a variable load current according to a condition of the load. A circuit portion for a regulator having an output terminal connected to a load including a variable load current may be provided. The circuit portion may include a plurality of stages connected in parallel to said output terminal. Each of said stages may be configured as a current driver having an output connected to the output terminal of said regulator. The circuit portion may include a comparator in each of said stages configured for receiving from a first input a reference voltage value and a predetermined threshold voltage from an other input. Each of said stages may receive a corresponding different threshold voltage value on said other input. The threshold voltage values may be correlated to the variable load current.
