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

Note:

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

Note: 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
