LM199/LM299/LM399/LM3999  
Precision Reference  
The LM199 series devices are packaged in a standard her-  
metic TO-46 package inside a thermal shield. The LM199 is  
rated for operation from −55˚C to +125˚C while the LM299 is  
rated for operation from −25˚C to +85˚C and the LM399 is  
rated from 0˚C to +70˚C.  
General Description  
The LM199 series are precision, temperature-stabilized  
monolithic zeners offering temperature coefficients a factor  
of ten better than high quality reference zeners. Constructed  
on a single monolithic chip is a temperature stabilizer circuit  
and an active reference zener. The active circuitry reduces  
the dynamic impedance of the zener to about 0.5Ω and al-  
lows the zener to operate over 0.5 mA to 10 mA current  
range with essentially no change in voltage or temperature  
coefficient. Further, a new subsurface zener structure gives  
low noise and excellent long term stability compared to ordi-  
nary monolithic zeners. The package is supplied with a ther-  
mal shield to minimize heater power and improve tempera-  
ture regulation.  
The LM3999 is packaged in a standard TO-92 package and  
is rated from 0˚C to +70˚C  
Features  
n Guaranteed 0.0001%/˚C temperature coefficient  
n Low dynamic impedance — 0.5Ω  
n Initial tolerance on breakdown voltage — 2%  
n Sharp breakdown at 400 µA  
n Wide operating current — 500 µA to 10 mA  
n Wide supply range for temperature stabilizer  
n Guaranteed low noise  
n Low power for stabilization — 300 mW at 25˚C  
n Long term stability — 20 ppm  
n Proven reliability, low-stress packaging in TO-46  
integrated-circuit hermetic package, for low hysteresis  
The LM199 series references are exceptionally easy to use  
and free of the problems that are often experienced with or-  
dinary zeners. There is virtually no hysteresis in reference  
voltage with temperature cycling. Also, the LM199 is free of  
voltage shifts due to stress on the leads. Finally, since the  
unit is temperature stabilized, warm up time is fast.  
The LM199 can be used in almost any application in place of  
ordinary zeners with improved performance. Some ideal ap-  
plications are analog to digital converters, calibration stan-  
dards, precision voltage or current sources or precision  
power supplies. Further in many cases the LM199 can re-  
place references in existing equipment with a minimum of  
wiring changes.
