Note: If the INHIBIT pin is left floating, the regulator is in the ON mode. However, to avoid picking
up any noise, it is suggested to ground it when the Inhibit function is not used.

1. Our SO-8 package used for voltage regulators is modified internally to have pins 2, 3, 6 and 7 electrically fused to the die
attach pad. 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.
