9 Power Supply Recommendations

Both inputs of the TPS7A88 are designed to operate from an input voltage range between 1.4 V and 6.5 V. The input voltage range must provide 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.
