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.
Data Sheet
THERMAL CHARACTERISTICS
The exposed paddle must be soldered to the ground plane for
the LFCSP package. Soldering the exposed paddle to the printed
circuit board (PCB) increases the reliability of the solder joints
and maximizes the thermal capability of the package.

4 Per JEDEC JESD51-8 (still air).
Typical θJA is specified for a 4-layer PCB with a solid ground
plane. As shown Table 7, airflow improves heat dissipation,
which reduces θJA. In addition, metal in direct contact with the
package leads from metal traces, through holes, ground, and
power planes reduces θJA.
