*For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating

conditions.

** All typical values except for parameter changes with temperature are at TA =25º C

***Duration of the short-circuit should not exceed one second.

****Standard deviation is a measure of the statistical distribution about the mean as derived from the formula.
