In noise sensitive applications, both conducted and radiated EMI can
be reduced significantly by controlling the MOSFET's turn-on and
turn-off times.

V CC = 15 V
The totem-pole outputs can furnish negative base current for enhanced
transistor turn-off, with the addition of capacitor C 1 .

Output Load Regulation
The capacitor's equivalent series resistance limits the Drive Output Current
to 1.5 A. An additional series resistor may be required when using tantalum or
other low ESR capacitors.
