1. Stresses above the absolute maximum rating may cause permanent damage to the device. Extended operation at the maxi-
mum levels may degrade performance and affect reliability.
2.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
3. Must be able to withstand the additional P
D
due to short circuit test, e.g. I
DS
. The P
D
number is based upon dc values.
