ZHCSN09A June 2021 – September 2022 LM5168-Q1 , LM5169-Q1
PRODUCTION DATA
EN/UVLO provides ON and OFF control for the LM516x-Q1. When VEN/UVLO is below approximately 0.45 V, the device is in shutdown mode. Both the internal linear regulator and the switching regulator are off. The quiescent current in shutdown mode drops to 3 μA at VIN = 24 V. The LM516x-Q1 also employs internal bias rail undervoltage protection. If the input voltage is below about 4.5 V, the regulator remains off.
