DESCRIPTIO
The LT®1029 is a 5V bandgap reference intended for use
in the shunt or “Zener” mode, allowing it to be used as
either a positive or negative reference. The output is
pretrimmed to ± 0.2% accuracy with 20ppm/°C maximum
temperature drift. A trim pin allows additional output
adjustment for even more precise output voltage.
Operating current range for the LT1029 is 700µA to 10mA.
Extremely low dynamic impedance allows excellent
output regulation even with fluctuating operating current.
The LT1029 will replace an LM136-5 or LM336-5 and
simplify circuits using the “minimum temperature coeffi-
cient” trim network. The LT1029 does not require this
special network to meet its temperature drift specification;
these application network components are simply
removed. If output trimming is required for initial
accuracy, the diodes in the trim network should be
replaced with jumpers.
