SNVS667I February 2010 – March 2022 LMZ12010
PRODUCTION DATA
The LMZ12010 will properly start up into a prebiased output. This start-up situation is common in multiple rail logic applications where current paths can exist between different power rails during the start-up sequence. Figure 7-1 shows proper behavior in this mode. Trace one is Enable going high. Trace two is 1.8-V prebias rising to 3.3 V. Trace three is the SS voltage with a CSS = 0.47 µF. Rise time is determined by CSS.
