5V Step Down Switching Regulator
Keep the switch node small by moving the inductor close to the switch node. This is only after placing all C
capacitors as close to their
IN
respective pins as possible. Make the L, C
loop small to limit the loop inductance and related noise. Place the C
such that the ground

end of the capacitor is close to the nearest ground pin (pin 6).
