Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to network ground terminal.

NOTES:
2. To calculate the minimum input voltage for your maximum output current, use the following formula:
VI(min) = VO(max) + VDO (max load)
3. Continuous output current and operating junction temperature are limited by internal protection circuitry, but it is not recommended
that the device operate under conditions beyond those specified in this table for extended periods of time.
