ADP150
PCB LAYOUT CONSIDERATIONS
Heat dissipation from the package can be improved by
increasing the amount of copper attached to the pins of the
ADP150. However, as listed in Table 7, 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 size or 0603 size capacitors
and resistors achieves the smallest possible footprint solution on
boards where area is limited.
