TDA3663 NXP Semiconductors Very low dropout voltage/quiescent current 3.3 V voltage regulator 11.3.1 Application circuit with backup function Sometimes a backup function is needed to supply, for example, a microcontroller for a short period of time when the supply voltage spikes to 0 V (or even −1 V). This function can easily be built with the TDA3663 by using an output capacitor with a large value.
