Certain Apex devices manufactured after 12/17/2013 (Date Code 1338 or later) have higher maximum quiescent
current (Iq) values than their datasheet specications. This is due to the replacement of an obsoleted component
inside those devices. See Table1 for affected device models and their old/new Iq values. See Fig. 1 for Date Code
identication.
Apex is in the process of redesigning the device to accommodate replacement component, returning Iq to original
values. This process is expected to be completed before 12/17/2014.
