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 LT3011 is tested and speci?ed for these conditions with the
ADJ pin connected to the OUT pin.
Note 3: 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 maximum input voltage, the output current range must be
limited. When operating at maximum output current, the input voltage
range must be limited.
Note 4: To satisfy requirements for minimum input voltage, the LT3011
is tested and speci?ed for these conditions with an external resistor
divider (249k bottom, 409k top) for an output voltage of 3.3V. The external
resistor divider will add a 5μA DC load on the output.
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 will be equal to (V IN – V DROPOUT ).
Note 6: GND pin current is tested with V IN = V OUT(NOMINAL) and a current
source load. This means the device is tested while operating close to its
dropout region. This is the worst-case GND pin current. The GND pin
current will decrease slightly at higher input voltages.
Note 7: ADJ pin bias current ?ows into the ADJ pin.
Note 8: SHDN pin current ?ows out of the SHDN pin.
Note 9: Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current ?ows into the OUT
pin and out the GND pin.
Note 10: The LT3011 regulators are tested and speci?ed under pulse
load conditions such that T J ? T A . The LT3011E regulators are 100%
tested at T A = 25°C. Performance of the LT3011E over the full –40°C
to 125°C operating junction temperature range is assured by design,
characterization and correlation with statistical process controls. The
LT3011I regulators are guaranteed over the full –40°C to 125°C operating
junction temperature range. The LT3011H is tested to the LT3011H
Electrical Characteristics table at 150°C operating junction temperature.
High junction temperatures degrade operating lifetimes. Operating lifetime
is derated at junction temperatures greater than 125°C.
Note 11: This IC includes overtemperature protection that is intended to protect
the device during momentary overload conditions. Junction temperature will
exceed 125°C (LT3011E/LT3011I) or 150°C (LT3011H) when overtemperature
protection is active. Continuous operation above the speci?ed maximum
operating junction temperature may impair device reliability.
