LDO Cout selection

Hi Shawn,

Capacitor requirements will vary by application and by the design decisions made internal to the LDO. As such, there is not a generic equation that can be given. Each datasheet will include the general requirements for both capacitance and ESR for the specific product.

This application report discusses the simplest method for checking stability by performing load transients:

You can learn more about capacitor vs capacitance from chapter 2 of our LDO Basics E-book:

Very Respectfully,
Ryan

Got it, thanks for your reply.
