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 specified 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 specification 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 specified 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 specified output current. In dropout, the

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 flows into the ADJ pin.

Note 8:

SHDN pin current flows 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 flows into the OUT

pin and out the GND pin.

Note 10: The LT3011 regulators are tested and specified under pulse

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 specified maximum

operating junction temperature may impair device reliability.
