7.3 Power Supply Recommendations

The input supply for the LDO must be within the recommended operating conditions (that is, between 2.2V to 5.5V). The input voltage must provide adequate headroom for the device to have a regulated output. If the input supply is noisy, additional input capacitors with low ESR can help improve the output transient performance.
