LAYOUT RECOMMENDATIONS
A proper layout is necessary for optimum performance of the
LM8207. A low impedance and clean ground plane is rec-
ommended. The traces from the V
pin to the ground plane
should be as short as possible. Decoupling capacitors
should be placed very close to the V
DD
pin. Connections of
these decoupling capacitors to the ground plane should be
very short.An additional decoupling capacitor for OUT_V
REF
is recommended.
Due to the heavy current peaks and short transitions at the
V
node, traces from the output of the V
buffer should
be low impedance and as short as possible, to minimize both
voltage drops over the trace and unwanted EM distur-
bances.
