... CAT6243 members are designed to block reverse current, meaning anytime V OUT FET will be shut off so there is no reverse current flow from output to input. CAT6243 is also equipped with an output discharge transistor that is turned ON anytime ENABLE logic Low. This transistor ensures when the regulator is shutdown. This is especially important when powering digital circuitry because if V fails to reach 0 V their POR (power− ...

... However, in the case where the CAT6243 is configured to provide a 0.8 V output, there is no resistor divider and the ADJ pin is connected to VOUT. If the part is enabled under no−load conditions, leakage current through the pass transistor at junction temperatures above 85° ...
