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 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
output voltage is 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 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 LT3014B is tested and specified under pulse load conditions
such that T

Performance at –40°C to 125°C is assured by design, characterization,
and statistical process controls. The LT3014BI is guaranteed over the full
–40°C to 125°C operating junction temperature range. The LT3014BMP is
100% tested and guaranteed over the –55°C to 125°C operating junction
temperature range.
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.
