Notes 1. The TYP. values are values at TA = 25

°C, except for the characteristics of temperature.

2. The short circuit output current flow must be terminated within 1 second.

Repeated operations are allowed while internal heat accumulation is within a safe range.

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