... Note 11: Adjust pin bias current flows out of the ADJ pin. Note 12: Shutdown pin current flows into the SHDN pin. Note 13: The LT3022 is tested and specified for this condition with an external resistor divider (3.92k and 5.9k) setting V resistor divider adds 50µA of load current. The specification refers to the change in the 0 ...

... If the output is held backup battery when the input is pulled to ground in a battery backup application, the LT3022 behaves diode is in series with its output, preventing reverse current flow. In dual supply applications where the regulator load is returned to a negative supply, pulling the output below ground by as much as 10V does not affect start-up or normal operation ...
