9 Power-Supply Recommendations

The TPS7A8300 is designed to operate from an input voltage supply range between 1.1 V and 6.5 V. The input voltage range provides adequate headroom in order for the device to have a regulated output. This input supply must be well regulated. If the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance.
