PCB Layout
Good PCB layout practices must be used, otherwise
instability can be induced because of ground loops and
voltages drops. The input and output capacitors must be
directly connected to the input, output, and ground pins
of the regulator using traces which do not have other
currents flowing in them.The best way to do this is to lay
out CIN and COUT near the device with short traces to the
VIN, VOUT, and ground pins. The regulator ground pin
should be connected to the external circuit ground so
that the regulator and its capacitors have a “single point
ground”.
