temperature and an application circuit board reference point for the thermal environment defined in Note 4. For
the MLP-8 package, the board reference is defined as the PCB copper connected to the thermal pad and
protruding from either end of the package. For the SOIC-8 package, the board reference is defined as the PCB
copper adjacent to pin 6.
