ADP124/ADP125

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 ADP124/

ADP125. However, as shown in Table 6, a point of diminishing

returns eventually is reached, beyond which an increase in the

copper size does not yield significant heat dissipation benefits.

The input capacitor should be placed as close as possible to the

VIN and GND pins, and the output capacitor should be placed

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 boards where the area is limited.
