Thermal consideration:
When power consumption is over about 1.2W( at 70
o
C ambient temperature), additional heat sink is required to control the
junction temperature below 125
C.

:
Thermal resistance from the junction to the mounting tab of the package.
θ
CS
:
Thermal resistance through the interface between the IC and the surface on which it is mounted. (typically,
θ

< 1.0°C / W)
θ
SA
:
Thermal resistance from the mounting surface to ambient (thermal resistance of the heat sink).
If PC Board copper is going to be used as a heat sink, below table can be used to determine the appropriate size of
copper foil required. For multi-layered PCB, these layers can also be used as a heat sink. They can be connected with
several through hole vias.
