10 Power Supply Recommendations

The TPS7A83A is designed to operate from an input voltage supply range from 1.1 V to 6.5 V. If the input supply is less than 1.4 V, then a bias rail of at least 3 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 may help improve output noise performance.
