TLV757P: Maximum Cout ESR value

Satoshi
Guru 19645 points
Part Number: TLV757P
Other Parts Discussed in Thread: MULTIPKGLDOEVM-823

Is there recommend maximum value for Cout's ESR on TLV757P? 

Or, is ESR_max value not have recommend limit and depend on design condition?

(For example, Vout, transient, accuracy, etc.)

Best regards,

Satoshi

    Hi Satoshi,

    TLV757P was designed, tested, and characterized for operation with ceramic capacitors which have low ESR. How much ESR are you anticipating in your application?

    You are correct that the best method to validate your intended output capacitors is to perform your worst case expected load transients while monitoring the output voltage on a scope. This will help you understand what performance you can expect. MULTIPKGLDOEVM-823 can be used early in your prototyping phase.

    Very Respectfully,

    Hi Satoshi,

    Since it has been a week without a reply, I assume that this thread is resolved. If this is not correct, please feel free to post again.
