Notes:

Our SO-8 package used for voltage regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die
attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power
when an appropriate area of copper on the printed circuit board is available for heat-sinking. The external dimensions are the
same as for the standard SO-8.
