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 LT3013 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 LT3013 is
tested and speci?ed for these conditions with an external resistor divider
(249k bottom, 649k top) for an output voltage of 4.5V. 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 = 4.75V and a current source
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 LT3013E 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 LT3013H is tested to the LT3013H Electrical Characteristics table at
140°C operating junction temperature. High junction temperatures degrade
operating lifetimes. Operating lifetime is derated at junction temperatures
greater than 125°C. The LT3013MP is 100% tested and guaranteed over
the –55°C to 125°C operating junction temperature range.
Note 11: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125°C (LT3013E, LT3013MP) or 140°C (LT3013H)
when overtemperature protection is active. Continuous operation above
the speci?ed maximum operating junction temperature may impair device
reliability.
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.
