(1)

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating

conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(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 4.6 V maximum if the output current rating is observed.
