Use the following general guidelines when designing printed
circuit boards:
1.
2.
3.
4.
Keep the output capacitor as close to the output and
ground pins as possible.
Keep the input capacitor as close to the input and ground
pins as possible.
PC board traces with larger cross sectional areas remove
more heat from the ADP3339. For optimum heat transfer,
specify thick copper and use wide traces.
The thermal resistance can be decreased by adding a
copper pad under the ADP3339, as shown in Figure 22b.

If possible, utilize the adjacent area to add more copper
around the ADP3339. Connecting the copper area to the
output of the ADP3339, as shown in Figure 22c, is best, but
thermal performance will be improved even if it is
connected to other pins.
Use additional copper layers or planes to reduce the
thermal resistance. Again, connecting the other layers to
the output of the ADP3339 is best, but is not necessary.
When connecting the output pad to other layers, use
multiple vias.
