The LMZ36002 is designed to operate from an input voltage supply range between 4.5 V and 60 V. This input supply should be well regulated and able to withstand maximum input current and maintain a stable voltage. The resistance of the input supply rail should be low enough that an input current transient does not cause a high enough drop at the LMZ36002 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 LMZ36002 additional bulk capacitance may be required in addition to the ceramic bypass capacitors. Typically, a 47 µF or 100 μF electrolytic capacitor will suffice.
