• Try to keep as many signals as possible on the inside layers of the board. If suitable ground flood fills are used on

the top and bottom layers, these will provide a good level of screening for noisy signals, both into and out of the

PCB.

• Ensure that the on-board regulators have sufficient tracking around and underneath the devices to act as a

heatsink. This heatsink will normally be connected to the 0 V or ground supply pin. Increasing the width of the

copper tracking to any of the device pins will aid in removing heat. There should be no solder mask over the

copper track underneath the body of the regulators.

• Ensure that the decoupling capacitors, especially high capacity ceramic type, have the requisite low ESR, ESL

and good stability/temperature properties. Refer to the regulator manufacturer’s datasheet for more information.
