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

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
VOUT and GND pins. Use of 0402 or 0603 size capacitors and
resistors achieves the smallest possible footprint solution on
