10 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.
