A voltage regulation system, particularly for a motor vehicle, adapted to be connected to a voltage source in order to provide a regulated voltage Vdd to at least one functional component F, the regulation system including a pre-regulator adapted to be connected to a voltage source and a regulator REG including at least one pre-regulation port PPR adapted to be connected to the pre-regulator and one functional port Pdd adapted to be connected to a functional component, the regulator including an adaptation device Q directly connecting the pre-regulation port to the functional port of the regulator, the adaptation device consisting of a single MOS power transistor including a drain D, a source S and a gate G. The MOS transistor includes an intrinsic diode DIODE between its drain and its source which is oriented to block the flow of a current between the functional port and the pre-regulation port.
