ADP225 UVLO Spec

Question asked by eli_az on Nov 16, 2014

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,
