Note 1:All typical Values except for temperature coefficient are at Ta=25°C.
Note 2:For conditions shown as MIN or MAX, use appropriate value under recommended operating conditions.
Note 3:Duration of the short-circuit should not exceed one second.
Note 4:Standard deviation is a measure of the statistical distribution the mean as derived from the formula:
