The invention relates to a circuit for supplying a consumer (10) with electric energy provided by a battery (11). The battery voltage (Ub) is prevented from falling below a predetermined minimum voltage (Umin) by a regulator (18) which adjusts the battery voltage (Ub) to a predetermined minimum voltage (Umin) by influencing the average amount of energy which is provided to the consumer (10). Preferably, the inventive circuit is used in a motor vehicle.
