OUTPUT LOAD (A)
All specifications are typical at nominal input, full load, and 25DegC unless
otherwise noted
* These are stress ratings. Exposure of the devices to any of these conditions
may adversely affect long term reliability. Proper operation under conditions
other than the standard operating conditions is neither warranteed nor implied.
