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 LT3029 is tested and speci?ed under pulse load conditions
such that T J ≈ T A . The LT3029E is 100% tested at T A = 25°C. Performance
of the LT3029E over the full –40°C to 125°C operating junction
temperature range is assured by design, characterization and correlation
with statistical process controls. The LT3029I is guaranteed over the full
–40°C to 125°C operating junction temperature range. The LT3029MP is
100% tested and guaranteed over the –55°C to 125°C operating junction
temperature range. The LT3029H is tested at 150°C operating junction
temperature. High junction temperatures degrade operating lifetimes.
Operating lifetime is derated at junction temperatures greater than 125°C.
Note 3: The LT3029 is tested and speci?ed for these conditions with the
ADJ1/ADJ2 pin connected to the corresponding OUT1/OUT2 pin.
Note 4: Maximum junction temperature limits operating conditions. The
regulated output voltage speci?cation does not apply for all possible
combinations of input voltage and output current. When operating at
maximum input voltage, limit the output current range. When operating at
maximum output current, limit the input voltage range.
Note 5: To satisfy minimum input voltage requirements, the LT3029 is
tested and speci?ed for these conditions with an external resistor divider
(two 243k resistors) for an output voltage of 2.437V. The external resistor
divider adds 5μA of DC load on the output.
Note 6: 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 equals: V IN – V DROPOUT .
