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
IN
capacitors as close to their
respective pins as possible. Make the L, C
OUT
loop small to limit the loop inductance and related noise. Place the C
OUT
such that the ground
end of the capacitor is close to the nearest ground pin (pin 6).
