Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. The input voltage and output negative-voltage ratings may be exceeded if the input and output current

ratings are observed.

3. The output positive-voltage rating may be exceeded up to 4.6V maximum if the output current rating is

observed.
