Input voltage, VI (see Note 2)
Continuous output current, IO (see Note 3)
Operating junction temperature, TJ
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.
