Product Details

The LT1029 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 coefficient” 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.
