The LMR14010A is designed to operate from an input voltage supply range between 4 V and 40 V. This input supply must be able to withstand the maximum input current and maintain a voltage above 4 V. The resistance of the input supply rail must be low enough that an input current transient does not cause a high enough drop at the LMR14010A supply voltage that can cause a false UVLO fault triggering and system reset. If the input supply is located more than a few inches from the LMR14010A, additional bulk capacitance can be required in addition to the ceramic input capacitors.
