ATL431: Output Unstable

Part Number: ATL431
Other Parts Discussed in Thread: TL431,

Dear Team,

My customer's output is unstable depending on the load current.

When the output voltage drop, the TL431 also not maintain at 2.5V.

Originally I thought is because of competitor's TL431 sink too much current.

So I suggest them to use ATL431, but the issue is the same.

Do you think smaller PR62 will help here?

I am worried if smaller PR62 solve the customer the issue, they will still use competitor's TL431.

Do you have any suggestion on it?
