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.

Test circuit
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.
