Part Number: TPS25940

Please let me know about determine Maximum Leak current below.

①Datasheet page-6 is described Output leak current, but two ways; source and sink.

　Which spec is should reference?

②For example, source current is -2μA~2μA, maximum leak current is 4μA, is it correct?

Hi Satoshi,

I'm going to move this to the appropriate forum.

Hi Satoshi,

If there is no voltage at output (Vout=0), the max. leakage variation is 4μA.
If you have powered bus at Vout and this device is in disable state, the maximum leakage would be 20μA.

Can you give us some information on your application use case to confirm which value of the two to consider

Regards,
Rakesh
