LM129/LM329  
Precision Reference  
The LM129 is packaged in a 2-lead TO-46 package and is  
rated for operation over a −55˚C to +125˚C temperature  
range. The LM329 for operation over 0˚C to 70˚C is available  
in both a hermetic TO-46 package and a TO-92 epoxy pack-  
age.  
General Description  
The LM129 and LM329 family are precision multi-current  
temperature-compensated 6.9V zener references with dy-  
namic impedances a factor of 10 to 100 less than discrete di-  
odes. Constructed in a single silicon chip, the LM129 uses  
active circuitry to buffer the internal zener allowing the de-  
vice to operate over a 0.5 mA to 15 mA range with virtually  
no change in performance. The LM129 and LM329 are avail-  
able with selected temperature coefficients of 0.001, 0.002,  
0.005 and 0.01%/˚C. These references also have excellent  
long term stability and low noise.  
Features  
n 0.6 mA to 15 mA operating current  
n 0.6Ω dynamic impedance at any current  
n Available with temperature coefficients of 0.001%/˚C  
n 7µV wideband noise  
A new subsurface breakdown zener used in the LM129 gives  
lower noise and better long-term stability than conventional  
IC zeners. Further the zener and temperature compensating  
transistor are made by a planar process so they are immune  
to problems that plague ordinary zeners. For example, there  
is virtually no voltage shift in zener voltage due to tempera-  
ture cycling and the device is insensitive to stress on the  
leads.  
n 5% initial tolerance  
n 0.002% long term stability  
n Low cost  
n Subsurface zener  
The LM129 can be used in place of conventional zeners with  
improved performance. The low dynamic impedance simpli-  
fies biasing and the wide operating current allows the re-  
placement of many zener types.
