8 Power Supply Recommendations

The LP38859 device is designed to operate from an input voltage supply range from 3 V and 5.5 V. The input voltage range provides adequate headroom in order for the device to have a regulated output. This input supply must be well regulated. An input capacitor of at least 10 μF is required.
