Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT3008 regulators are tested and speci?ed under pulse
load conditions such that T J ? T A . The LT3008E is guaranteed to meet
performance speci?cations from 0°C to 125°C operating junction
temperature. Speci?cations over the –40°C to 125°C operating junction
temperature range are assured by design, characterization and correlation
with statistical process controls. The LT3008I is guaranteed over the full
– 40°C to 125°C operating junction temperature range. The LT3008MP is
100% tested and guaranteed over the –55°C to 125°C operating junction
temperature range.
Note 3: The LT3008 adjustable version is tested and speci?ed for these
conditions with the ADJ pin connected to the OUT pin.
Note 4: Operating conditions are limited by maximum junction
temperature. The regulated output voltage speci?cation will not apply
for all possible combinations of input voltage and output current. When
operating at the maximum input voltage, the output current range must be
limited. When operating at the maximum output current, the input voltage
Note 5: Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a speci?ed output current. In dropout, the
output voltage equals (V IN – V DROPOUT ). For the LT3008-1.2 and LT3008-
1.5, dropout voltage will be limited by the minimum input voltage.
Note 6: To satisfy minimum input voltage requirements, the LT3008
adjustable version is tested and speci?ed for these conditions with an
external resistor divider (61.9k bottom, 280k top) which sets V OUT 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 V IN = V OUT(NOMINAL) + 0.55V and
a current source load. GND pin current will increase in dropout. For the
?xed output voltage versions, an internal resistor divider will add about
1μA to the GND pin current. 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.
