    Hello,
    
 
    I am using the ADP225ACPZ-R7 regulator, and I have noticed something strange 
     with the feature "UVLO - falling edge": It says on the datasheet that the 
     minimum voltage for shutdown is 2.2V, and instead it shuts down at 2.17V.
     This occured in more than one device.
     I have checked on another regulator ADP150AUJZ-3.0 and there the shutdown 
     occured above the lower limit.
     
     How is the UVLO feature supposed to work? What is the correct way to measure 
     this spec?
     
     Thank you,
     Eli.
