SBVS233B January 2016 – June 2021 TPS7A84
The TPS7A84 is designed to operate from an input voltage supply range between 1.1 V and 6.5 V. If the input supply is less than 1.4 V, then a bias rail of at least 3.0 V must be used. 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 output noise performance.
