LT3008
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TJ = 25°C. (Note 2)
Note 6: To satisfy minimum input voltage requirements, the LT3008
adjustable version is tested and specified for these conditions with an
external resistor divider (61.9k bottom, 280k top) which sets VOUT to 3.3V.
The external resistor divider adds 9.69μA of DC load on the output. This
external current is not factored into GND pin current.
Note 7: GND pin current is tested with VIN = VOUT(NOMINAL) + 0.5V and a
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.
