Pre-Biased Startup
PRE-BIASED STARTUP
The LMZ14203 will properly start up into a pre-biased output.
This startup situation is common in multiple rail logic applica-
tions where current paths may exist between different power
rails during the startup sequence. The following scope cap-
ture shows proper behavior during this event.
