LMZM33606: LMZM33606 COUT capacitor for 12V output 50uF or 100uF ?

Hi Jimmy,

Could you explain your recommendation which was given in this thread ?

"LMZM33606 COUT capacitor slection help"

e2e.ti.com/.../2894677

Your reply was "Following Table 3 datasheet recommendation, for Vout=12V application, the output capacitance should be at minimum 50uF and be rated for at least 25V which is twice the output voltage rating. "

Current version of DS has Table 3 where for Vout=12V 100uF are required. Only for >12 and <=20 50uF is allowed.

Because of capacitor DC bias derating at 12V it is important because it leads to 6 vs 12 caps difference.

We are planning to use LMZM33606 for 12V output in our design.

Could you provide some clarification about value recommended by you and provided in datasheet ?

Thanks a lot!
