PCB LAYOUT CONSIDERATIONS
Heat dissipation from the package can be improved by increasing
the amount of copper attached to the pins of the ADP16x. 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.
