A power supply circuit () for a switching voltage regulator () connectable to a load () is described. In order to manage a power consumption of the switching voltage regulator () and in particular to minimize a power consumption of the switching voltage regulator when being operative, the power supply circuit () is configured for selectively supplying the switching voltage regulator () with one of a first input voltage and a second input voltage in response to a control signal indicative of an operative state of the load () such that the switching voltage regulator () is switched between a working state in response to the first input voltage and a standby state in response to the second input voltage.
