1. 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 heatsinking. The external

dimensions are the same as for the standard SO-8.

Note:

If the Inhibit pin is left floating, the regulator is in ON mode. However, to avoid any noise

picking-up, it is suggested to ground it when the Inhibit function is not used.
