Connect C
IN
between V
IN
of the ILC7080/81 and the
“GROUND PLANE”.
Keep the ground side of C
OUT
and C
NOISE
connected to
the “LOCAL GROUND” and not directly to the
“GROUND PLANE”.
On multilayer boards use component side copper for
grounding around the ILC7080/81 and connect back to a
“GROUND PLANE” using vias.
If using a DC-DC converter in your design, use a star
grounding system with separate traces for the power
ground and the control signals. The star should radiate
from where the power supply enters the PCB.
Place all RF LDO related components; ILC7080/81,
input capacitor C
IN
, noise bypass capacitor C
NOISE
and
output capacitor C
OUT
as close together as possible.
Keep the output capacitor C
OUT
as close to the
ILC7080/81 as possible with very short traces to the
V
OUT
and GND pins.
The traces for the related components; ILC7080/81,
input capacitor C
IN
, noise bypass capacitor C
NOISE
and
output capacitor C
OUT
can be run with minimum trace
widths close to the LDO.
Maintain a separate “LOCAL GROUND” remote from
the “GROUND PLANE” to ensure a quiet ground near
the LDO.
Figure 9 shows how this circuit can be translated into a
PCB layout.
