PRINTED CIRCUIT BOARD LAYOUT

CONSIDERATIONS

Heat dissipation from the package can be improved by increasing

the amount of copper attached to the pins of the ADP322/

ADP323. However, as can be seen from Table 7, a point of

diminishing returns is eventually reached, beyond which an

increase in the copper size does not yield significant heat

dissipation benefits.

Place the input capacitor as close as possible to the VINx and

GND pins. Place the output capacitors as close as possible to

the VOUTx and GND pins. Use 0402 or 0603 size capacitors

and resistors to achieve the smallest possible footprint solution

on boards where area is limited.
