ABSOLUTE MAXIMUM RATINGS
(*) 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 appro-
priate 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.
