Application Hints

To get the best possible performance from the LMV8172T it

is important to use a good PCB layout and the correct com-

ponents. The 0.1 µF and 470 µF capacitors on the V

CC1 and

EE lines should be as close as possible to their pins. The

power traces should be wide and there should be no jumpers

between the capacitors and the LMV8172T. The value of the

electrolytic capacitors used on the V

CC1

and V

lines

should be 470 µF or greater. The ground traces should also

be as wide as possible. The diode and optional capacitor

should be located close to the LMV8172T. The diode should

be a fast-recovery type, the 1N4937 recommended has a t

of 150 ns. The capacitor is optional, it may be needed in

some PCB layouts. A suggested layout is shown in

Figure 6.
