Notes:
1. T

2. Over full operating temperature range.
3. Guaranteed, not tested
4. The short circuit current is less than the maximum output current due to internal foldback current limiting.
The -5V and -5.2V versions do not reach the foldback current limit and therefore conducts a higher short
circuit level.
