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.
If you use the ADP5304-EVALZ, there is a regulator diode D3 at PVIN so that may increase the input current. If you don't use the VINOK function, you can try ADP5300. The quiescent would be around 180nA.
