Power Supply Recommendations

The LP2992 is designed to operate from an input voltage supply range from 2.2 V to 16 V. The input voltage range provides the 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 to improve the output noise performance.
