PCB LAYOUT CONSIDERATIONS

Place the input capacitor as close as possible to the VIN pin and

ground. Place the output capacitor as close as possible to the

VOUT pin and ground. Place the bypass capacitors (CREG, CREF,

and CBYP) for VREG, VREF, and VBYP close to the respective pins

(VREG, REF, and BYP) and ground. The use of a 0805, a 0603,

or a 0402 size capacitor achieves the smallest possible footprint

solution on boards where area is limited. Maximize the amount of

ground metal for the exposed pad, and use as many vias as

possible on the component side to improve thermal dissipation.
