SNVS610P December 2009 – April 2019 LMZ10504
PRODUCTION DATA.
The LMZ10504 features an enable (EN) pin and associated comparator to allow the user to easily sequence the LMZ10504 from an external voltage rail, or to manually set the input UVLO threshold. The turnon or rising threshold and hysteresis for this comparator are typically 1.23 V and 0.15 V, respectively. The precise reference for the enable comparator allows the user to ensure that the LMZ10504 will be disabled when the system demands it to be.
The EN pin should not be left floating. For always-on operation, connect EN to VIN.
