Stresses beyond those listed under "absolute maximum ratings" cause permanent damage device. These stress ratings only, functional operation device these other conditions beyond those indicated under "recommended operating conditions" implied. Exposure absolute-maximum-rated conditions extended periods affect device reliability. NOTES: input output voltage ratings exceeded input output current ratings observed. package thermal impedance calculated accordance with JESD except through-hole packages, which trace length zero.
