Part Number: LMZM33603
Hi,Let's discuss the output capacitor of LMZ33603 and LMZ33606.Customers want to install ceramic cap and electrolytic cap in Vout.However, the data sheet recommends POS cap.Please advise design guidelines when selecting ceramic cap and electrolytic cap.Best Regards,Yusuke
Pls provide more information about P/N and Q'ty of output capacitors will be used, we can estimate loop stability with these caps accordingly.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Andy Chen:
You may expect to have higher ESR when using aluminum electrolytic capacitors as opposed to aluminum polymer capacitors. This may impact your stability.
I would recommend using the Webench designer tool on the product folder if you want to test out different capacitor value and type. The designer tool should help provide design guidance through simulation. Also testing it with the LMZM33603EVM will definitely give you more information on the performance. There is a convenient footprint (C10) for you to test different types of capacitor to your choosing.
