Hello there, I’m just an electronic hobbyist. So I read the LM2940 datasheet 1 and know that I need two capacitors, and they must also be rated higher than my voltages as well.Now I’m confused about ESR and capacitor type, how to choose them?Because ESR isn’t listed on data sheets, at least not on the ones I’m looking at.Btw do you guys have any more specific introduction to LM2940, all I can found on the internet which introduces it more in details is this article:https://www.apogeeweb.net/circuitry/lm2940-pinout-datasheet.html, but it doesn’t have the answer to my question.Thank you in advance.
