1 Values relate to package being used on a standard 2-layer PCB. This gives a
worst-case θJA and θJC. See Figure 4 for a plot of maximum power dissipation
vs. ambient temperature (TA).
2 TA = ambient temperature.
3 Junction-to-case resistance is applicable to components featuring a
preferential flow direction, for example, components mounted on a heat
sink. Junction-to-ambient is more useful for air-cooled, PCB-mounted
components.

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