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.
