ABSTRACT:
A low drop-out DC voltage regulator regulates a voltage from a DC supply and includes: a pass device controllable to maintain a voltage at an output of the regulator and arranged to provide a first current from the DC supply, at least part of said first current being provided to a load coupled to the output of the regulator; and a current regulator coupled to said pass device and to the output of the regulator. The current regulator is arranged to conduct a second current controllable such that the first current through said pass device remains constant irrespective of variations in a load current to said load.
