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.
