Described herein is an apparatus (30) for regulating voltages across a plurality of loads (21, 23). The apparatus comprises a first linear regulator (35) for regulating a first voltage across a first load (23) and a second linear regulator (37) for regulating a second voltage across a second load (21). The apparatus also has a current recycling node (33) provided between an output of the second linear regulator (37) and an input of the first linear regulator (35) such that, in use, a total current drawn by the apparatus is less than a sum of a current flowing in the first load and a current flowing in the second load.
