ELECTRICAL CHARACTERISTICS

The

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 LT3014B 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 LT3014B

is tested and specified for these conditions with an external resistor divider

(249k bottom, 392k top) for an output voltage of 3.3V. The external

resistor divider adds a 5

µA 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 in its dropout

region. This is the worst-case GND pin current. The GND pin current

decreases slightly at higher input voltages.

Note 7: ADJ pin bias current flows into the ADJ pin.

Note 8: 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 of the GND pin.

Note 9: The LT3014BE is guaranteed to meet performance specifications

from 0

°C to 125°C operating junction temperature. Specifications over

the –40

°C to 125°C operating junction temperature range are assured by

design, characterization and correlation with statistical process controls.

Note 10: This IC includes overtemperature protection that is intended to

protect the device during momentary overload conditions. Junction

temperature will exceed 125

°C when overtemperature protection is

active. Continuous operation above the specified maximum operating

junction temperature may impair device reliability.
