Hello, 

I have attached my design, Where we connected MAX16009's output having sink current( 2mA)to LMZ12002 enable pin.

As i read from datasheet  LMZ12002 it says it has internal pull-up resistor ,So when Vin comes  LMZ12002 will be on if enable pin is not grounded(sinked).

My design needs to hold the EN pins of  LMZ12002 to grounded by   MAX16009 .

So my question is how much sink current needed to drive the enable pin of  LMZ12002  "LOW".

Waiting for your feedback since my design is in crucial stage. 

Regards,

Prasanna G
