Hello,

I was wondering around what value the optional capacitors in the matching circuit should be? A simple question I'm sure.

Thanks,

Chris

Hello Chris,

Using my best conservative design practice, I would use 10uF ceramic caps for the input and output capacitors. I would use a 10nF ceramic capacitor for the noise reduction capacitor, Cnr. And, if I were using the adjustable version of the LDO and decided to use a 100kohm resistor for the R1 (top) feedback resistor then I would use a 1nF ceramic feedback capacitor (Fig 32).
