8.4 Power Supply Recommendations

These devices are designed to operate from an input voltage supply range between –10V and –2.7V. 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. If the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance.
