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 LT3023 is tested and specifi ed under pulse load conditions
such that T
at – 40°C and 125°C is assured by design, characterization and correlation
with statistical process controls. The LT3023I is guaranteed over the full
–40°C to 125°C operating junction temperature range.
Note 3: The LT3023 is tested and specifi ed for these conditions with the
ADJ1/ADJ2 pin connected to the corresponding OUT1/OUT2 pin.
Note 4: Operating conditions are limited by maximum junction
temperature. The regulated output voltage specifi 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 5: To satisfy requirements for minimum input voltage, the LT3023 is
tested and specifi ed for these conditions with an external resistor divider
(two 250k resistors) for an output voltage of 2.44V. The external resistor
divider will add a 5μA DC load on the output.

Note 6: Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a specifi ed output current. In dropout, the
output voltage will be equal to: V
Note 7: GND pin current is tested with V
load. This means the device is tested while operating in its dropout region
or at the minimum input voltage specifi cation. This is the worst-case GND
pin current. The GND pin current will decrease slightly at higher input
voltages.
Note 8: ADJ1 and ADJ2 pin bias current fl ows into the pin.
Note 9: SHDN1 and SHDN2 pin current fl ows into the pin.
Note 10: Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current fl ows into the OUT
pin and out the GND pin.
Note 11: For the LT3023 dropout voltage will be limited by the minimum
input voltage specifi cation under some output voltage/load conditions.

Characteristics.
