Note 6: To satisfy minimum input voltage requirements, the LT3008

adjustable version is tested and specified for these conditions with an

The external resistor divider adds 9.69μA of DC load on the output. This

external current is not factored into GND pin current.

current source load. GND pin current will increase in dropout. See the GND

Pin Current curves in the Typical Performance Characteristics section.

Note 8: The SHDN pin can be driven below GND only when tied to the IN

pin directly or through a pull-up resistor. If the SHDN pin is driven below

GND by more than –0.3V while IN is powered, the output will turn on.

Note 9: Output noise is listed for the adjustable version with the ADJ pin

connected to the OUT pin. See the RMS Output Noise vs Load Current

curve in the Typical Performance Characteristics Section.
