Design Hints
V_IN and GND printed circuit board traces should be as
wide as possible. When the impedance of these traces is high
due to narrow trace width or long length, there is a chance
to pick up noise or cause the regulator to malfunction. Place
external components, especially the input and output
capacitors, as close as possible to the CAT6242, and keep
traces between power source and load as short as possible.
