"Splet14. nov. 2024 · A good, but expensive, way to reduce power-supply noise is to put a second low-noise regulator on the power-supply output. This often involves a low-dropout (LDO) linear regulator. It will reduce any output ripple by an order of magnitude or more. Better yet, you can add an RC or LC filter after the LDO to reduce noise even further. " - Switching power supply noise filter

Splet12. nov. 2024 · Output Noise in Switching Regulators By their nature, there will be some switching noise on the output of a nSMPS. After all, they are designed to switch the current from a higher DC source using a pulse-width-modulated (or pulse-frequency-modulated) signal, and then filter this using a 2-pole LC filter. Spletalized, and the problem of switching power supply noise is pervasive. Reducing noise with a conventional single-stage filter seldom works. The inductor is already large, and drop-ping the noise an order of magnitude just isn’t feasible. For this reason, many designers add a second “noise” filter at the output of their power supply.
