ABSTRACT:
The invention relates to a method to reduce the power consumption of an electronic device comprising at least one voltage regulator. At least one of the regulators (REG1-REG4) is switched off and on according to a predetermined duty cycle during such periods when the electronic device does not require the normal power supply ability of the regulator. This may be realized e.g. in a mobile phone during two successive control channel messages received from a base station when the mobile phone is in a so called power saving mode.
