No-load quiescent current of ADP5304

Hello,

 

I have a question about the quiescent current of ADP5304.

 

The output is set to 1.8 volts and the input is 3.6 volts.

 

For the sake of meeting the spec about 180 nA with occasional switching, there were some common mistakes that I try to avoid.

 

1. There is no probe connected with input & output node 

2. Use DMM ( 34465A ) 's smooth filter function 

 

However the lowest quiescent current from my measure result is about 280 nA. ( The attachment shows my average result )

 

Is there something I should do to meet the spec ?

 

Thanks for sharing the information.

 

Ian.
