SS8014G

Layout Guide

An input capacitance of ~1µF is required between the

SS8014 input pin and ground (the amount of the capaci-

tance may be increased without limit), This capacitor

must be located a distance of not more than 1cm from

the input and return to a clean analog ground.

This input capacitor filters out the input voltage spike

caused by the surge current due to the inductive effect

of the package pin and the printed circuit board’s rout-

ing wire. Otherwise, the actual voltage at the IN pin

may exceed the absolute maximum rating.

The output capacitor also must be located a distance

of not more than 1cm from output to a clean analog

ground. This capacitor filters out the output spike

caused by the surge current due to the inductive effect

of the package pin and the printed circuit board’s rout-

ing wire. Figure 3 is the suggested PCB layout of SS8014.
