7.3.4 VDD

The TPS38800-Q1/TPS388R0-Q1 is designed to operate from an input voltage supply range between 2.6V to 5.5V. An input supply capacitor is not required for this device; however, if the input supply is noisy good analog practice is to place a 1µF capacitor between the VDD pin and the GND pin.

VDD needs to be at or above VDD(MIN) for at least the start-up delay (tSD+ tD) for the device to be fully functional.
