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 ADP1712/
ADP1713/ADP1714. However, as can be seen from Table 5, a
point of diminishing returns eventually is 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 IN and GND
pins. Place the output capacitor as close as possible to the OUT
and GND pins. For the ADP1712 adjustable version, place the
soft-start capacitor as close as possible to the SS pin. For the
ADP1713, place the internal reference bypass capacitor as close
as possible to the BYP pin. Use of 0402 or 0603 size capacitors
and resistors achieves the smallest possible footprint solution on
boards where area is limited.
