Notes
1. Stresses beyond those listed 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 instructions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
