ADP222/ADP223/ADP224/ADP225
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
ADP222/ADP223/ADP224/ADP225. However, as listed in
Table 6, 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 VIN and
GND pins. Place the output capacitor as close as possible to the
VOUTx and GND pins. Use of 0402 or 0603 size capacitors and
resistors achieves the smallest possible footprint solution on
boards where area is limited.
