... Sometimes a backup function is needed to supply, for example, a microcontroller for a short period of time when the supply voltage spikes (or even 1 V). This function can easily be built with the TDA3668AT by using an output capacitor with a large value. When the supply voltage (or 1 V), only a small current will flow into pin REG from this output capacitor (a few A) ...
