Hi,
Good day.
Our customer would like to know how large is leakage current from OUT pin when the switch is disabled?
Thanks,
Cedrick

Hi Bob,
Thank you for this information.
you mentioned "reverse leakage current". I guess that this is a current which flows into OUT pin when pin IN = ground.
However I am interested in a current which flows from OUT pin (from TPS2052B) when IN = 5 V and EN = 0 V (switch disabled).
Can you please help me here?
Thanks,
Cedrick
Hi, Cedrick,
These should be same. During both condition, the switch is disabled and the current is measured from OUT pin. I don't think the IN=GND or IN=5V will make difference because when IN=GND, the reverse current is already 0.

Hi Bob,
Good day.
I've got a response from our customer, kindly see below.
thank you for the feedback.
I was doing some measurements with TPS2052B.
Voltage of 5 V was present at IN pin and 0 V at EN pin (switch diasbled). There was only capacitive load at the output (about 50 uF) and I observed that the output voltage was slowly increasing. That is why I thought that there must be at least some minimal leakage current from OUT pin which charges the output capacitors.
What do you think?
Regards,
Cedrick
Hi Cedrick,
If there is constant leakage current, the output voltage should increase until 5V.
So I think it's just some static charging.
