3. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Package thermal resistance is measured on the ATR0881 demo board without heat spreader. Users should ensure that the
junction temperature never exceeds 150°C. Thermal resistance from junction to case and to ambient depends very much on
the PCB layout and on heat spreading measures.
