TPS24751 Cout value at using as Load Switch

Other Parts Discussed in Thread: TPS24751

Hi,

My customer is using TPS2475 as Load Switch.
This is showed by Application note, Fgiure2.
www.tij.co.jp/.../slua740.pdf

At this condition, 470uF output capacitor is used at Figure2.
Why does TSP2475x need the big capacitor as output cap?
Customer wants to use 100~150uF ceramic capacitor.
Can customer use the 100~150uF ceramic capacitor as output cap?

Best regards,
Shimizu

Sorry for the delay. I've moved this to the load switch forum.

You can change Cout. Please refer to the spreadsheet design tool (online) for guidance about how to size the other components based on Cout.

Hi Shimizu,

100~150uF ceramic capacitor can be used without any issue.
