LT1029CZ#PBF

LT1029CZ#PBF 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. Extremely low dynamic impedance allows excellent output regulation even with fluctuating operating current. It will replace an LM136-5 or LM336-5 and simplify circuits using the “minimum temperature coefficient” trim network. Device 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. Application includes A-to-D and D-to-A converters, precision regulators, precision current sources, V to F and F to V converters.

• Temperature stability is 5mV typical (TA=25°C, IR=1mA, TA=25°C)
• Typical long term stability is 20ppm/KHr (TA=25°C)
• Trim range is +3% minimum (TA=25°C)
• TO-92 plastic package
• Operating temperature range from 0°C to 70°C
