To calculate the minimum input voltage for your maximum output current, use the following equation: V
I(min)
= V
O(max)
+ V
DO(max load)
.
NOTE 2: Continuous 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.
