Notes
1. Stresses beyond those listed may cause permanent damage to the device. These are stress rating only and
functional operation of the device at these or any other conditions beyond those under ‘recommended operating
conditions’ 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.
