Layout Guide
An input capacitance of
1μF is required between the
G913 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.

Input capacitor can filter 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
routing 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. Because it can filter out the output spike
caused by the surge current due to the inductive effect
of the package pin and the printed circuit board’s
routing wire. Figure 6 is adjustable mode of G913 PCB
layout. Figure 7 is a PCB layout of G913 fixed mode.
