Heat dissipation from the package can be improved by increasing

the amount of copper attached to the pins of the ADP151. 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 the

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

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

resistors achieves the smallest possible footprint solution on boards

where area is limited.
