performance. The significant feature of this device is the
exposed copper pad on which the power die is soldered. This
pad is soldered on a PCB to provide heat flow to ambient and
also to provide thermal capacitance. The more copper area
on the PCB, the better the power dissipation and transient
behavior will be.
