However, if logic-level transistors or transistors with low
V
GS(on)
are used, close attention to layout guidelines should
be exercised, as the low gate threshold could lead to some
shoot-through despite counteracting circuitry present aboard
the ISL6529.
N-Channel MOSFET Transistor Selection
The main criteria for selection of the linear regulator pass
transistor is package selection for efficient removal of heat.
Select a package and heatsink that maintains the junction
temperature below the rating with a maximum expected
ambient temperature.
The power dissipated in the linear regulator is:
where I
O
is the maximum output current and V
OUT
is the
nominal output voltage of the linear regulator.
