Application Information
It is very important to keep the lead lengths to a minimum
and to provide a low impedance current path by using a
ground-plane on the board.
Caution: If R
of LM7121 would be disturbed and it would have to supply
the full amount of load current. This might damage the part if
power dissipation limit is exceeded.
L
is removed, the current balance at the output
