PCB LAYOUT CONSIDERATIONS

Heat dissipation from the package can be improved by increasing

the amount of copper attached to the pins of the ADP160/ADP161.

However, as listed in Table 8, a point of diminishing returns is

reached eventually, 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 VIN and

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

VOUT and GND pins. Use of 0402 or 0603 size capacitors and

resistors achieves the smallest possible footprint solution on

boards where area is limited.
