App note: Minimizing switching regulator residue in linear regulator outputs

Posted on Sunday, August 12th, 2012 in app notes by DP

Here is an app note from Linear Technology describing how to minimize switching regulator noise in linear regulator outputs.

Linear regulators are commonly employed to post-regulate switching regulator outputs. Benefi ts include improved stability, accuracy, transient response and lowered output impedance. Ideally, these performance gains would be accompanied by markedly reduced switching regulator generated ripple and spikes. In practice, all linear  egulators encounter some diffi culty with ripple and spikes, particularly as frequency rises.

    Lol, the last page! Linear Technologies is awesome!

  2. The link to the pdf doesnt work the new link is: http://cds.linear.com/docs/en/application-note/an101f.pdf

    cheers
