The device is designed to operate from an input voltage supply range from 2.8 V and 5.5 V. This input supply must be well regulated and can withstand maximum input current and keep a stable voltage without voltage drop even at load transition condition. The resistance of the input supply rail must be low enough that the input current transient does not cause too high drop in the LP8756x-Q1 supply voltage that can cause false UVLO fault triggering. If the input supply is located more than a few inches from the LP8756x-Q1 additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
