9 Power Supply Recommendations

The LM3263 device is designed to operate from an input voltage supply range from 2.7 V to 5.5 V. This input supply should be well-regulated and able to withstand maximum input current and maintain stable voltage without voltage drop even under largest load transition conditions.
