9 Power Supply Recommendations

The LP2983 is designed to operate from an input voltage supply range between 2.2 V and 16 V. The input voltage range provides adequate headroom 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 and transient performance.
