TLV704: Any ESR standard for input/output capacitor?

Hung Ching Hsu
Expert 3086 points
Part Number: TLV704

Hi Team

My customer asked that, is there any ESR standard for input/output capacitor?

The customer is using TLV70450DBVR (Recommended input/output capacitor capacity: 1uF or more)

Generally, I think that there is an ESR standard for LDO, but is there an ESR standard for this device?

I'm asking because I can't find the information in the datasheet.

It is said that ceramic capacitors are recommended, but how about the ESR standard?



Best Regards,

    HI Hung Ching,

    Typically that input capacitor is not required for stability. As for the output capacitor we typically simulate with a minimum ESR of around 20mOhms. the reason we emphasize ceramic capacitors are simply that they are typically smaller and cheaper than other dielectrics. I updated this app note to help clarify ESR and its impact on stability. 

    Does this help to answer your question?
