Grounding Recommendations
1. Connect C
IN
between V
IN
of the ILC7083 and the
“GROUND PLANE”.
2. Keep the ground side of C
OUT
and C
NOISE
connected to
the “LOCAL GROUND” and not directly to the
“GROUND PLANE”.
3. On multilayer boards use component side copper for
grounding around the ILC7083 and connect back to a
“GROUND PLANE” using vias.
4. 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.
Layout Considerations
1. Place all RF LDO related components; ILC7083, input
capacitor C
IN
, noise bypass capacitor C
NOISE
and output
capacitor C
OUT
as close together as possible.
2. Keep the output capacitor C
OUT
as close to the ILC7083
as possible with very short traces to the V
OUT
and GND
pins.
3. The traces for the related components; ILC7083, 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.
4. 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.
