10 Power Supply Recommendations

The output of a switching regulator typically will contain a small ripple voltage at the switching frequency and may also contain voltage transients. These transient voltage spikes can be sensed by the LM3411 and could give an incorrect regulation voltage. An RC filter consisting of a 1-Ω resistor and a 100-nF capacitor will filter these transients and minimize this problem.
