(1) Operation outside the Absolute Maximum Ratings may cause
permanent device damage. Absolute Maximum Ratings do not imply functional
operation of the device at these or any other conditions beyond those listed
under Recommended Operating Conditions. If used outside the Recommended
Operating Conditions but within the Absolute Maximum Ratings, the device may not
be fully functional, and this may affect device reliability, functionality,
performance, and shorten the device lifetime .
Note: The input and output voltage ratings may be exceeded if the input and output
current ratings are observed. The package thermal impedance is calculated in accordance
with JESD 51-7.5.2 ESD Ratings
