Hi Hen,

There is no listed maximum output capacitor, but placing to large of an output capacitor may cause some problems during startup like going into current limit and creating a large inrush current. What is the output capacitor you are looking at using?

Best Regards,

I want to use output 47uF X7R ceramic capacitor with this part.

Also I`m using LP5910-1.0DRVR , can i use 47uF X7R ceramic capacitor? if not what is the maximum value?

Thanks

Hi Hen,

The 47uF should be fine for the TPS735, but just watch out for the other side effects of increasing the output capacitor I mentioned earlier. There is another post e2e.ti.com/.../653910 covering the LP5910.

Best Regards,
Mark
