Stresses beyond those listed in the table below 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 in “Electrical
Characteristics” on page 6 is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

ºC/W
Junction-to-ambient thermal resistance is very
dependent on application and board-layout. In
situations where high maximum power
dissipation exists, special attention must be
paid to thermal dissipation during board
design.
