SNVS690I January 2011 – August 2021 LMZ14201H
The LMZ14201H will properly start up into a prebiased output. This startup situation is common in multiple rail logic applications where current paths may exist between different power rails during the startup sequence. The prebias level of the output voltage must be less than the input UVLO set point. This will prevent the output prebias from enabling the regulator through the high-side MOSFET body diode.
