Abstract
Abstract The invention relates to a method to reduce the power consumption of an electronic device comprising at least two voltage regulators. At least one of the regulators (REG2-REG4) is switched off, and the output of at least one regulator still switched on is connected to the output (OUT2-OUT4) of the at least one regulator switched off, in order to supply power to said at least one output (OUT2-OUT4).
