    Hello,
    

    I'm a DFAE in Japan. Our customer evaluates LT3065 and has a question about Internal current limit. What's meaning ΔVout=-5%?
    

     
    

    Regards,
    

    Hiroyuki

      Thanks for the post.  The specified Internal Current Limit you show above is the guaranteed minimum current the regulator can provide without the output voltage decreasing by more than 5%.  I show the behavior in the image below.   In my example, internal current limit will cause the output voltage to drop from 0.6V to 0.54 when the output current is 900mA.
