9 Power Supply Recommendations

These devices are designed to operate from an input voltage supply range from 2.7 V to 5.5 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 and stable. A 0.1-µF input capacitor is required for stability; if the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance.
