9 Power Supply Recommendations

The LM3535 is designed to operate from an input voltage supply range between 2.7 V and 5.5 V. This input

supply must be well regulated and capable to supply the required input current. If the input supply is located far

from the LM3535 additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
