Abstract

A circuit arrangement for monitoring the current supply of an electric consumer has a voltage regulator connected to an operating voltage that is variable over time and has a voltage monitor for switching on a consumer exclusively during the constant phase of the supply voltage. The voltage monitor is defined by a comparator at one input of which a reference voltage proportional to the regulator output voltage is present and at the other input of which a difference voltage picked up at the regulator output and exceeding a threshold value is present. A switch-on and switch-off signal can be take off at the comparator output.
