    Abstract: A low-power-mode unit connected in parallel with a low-dropout regulator to provide a low-power mode includes a power P-MOS transistor, a differential amplifier, and an analog synchronization loop. The analog synchronization loop is configured to add a variable voltage offset depending on a total current at the output such that, in a high-power mode, the low-power unit current flowing through the P-MOS transistor is not zero, while being substantially smaller than the low-dropout regulator current flowing through the low-dropout regulator, and smaller than a predetermined value.
