PRECISION REFERENCE  
General Description  
The LM129 is a precision multi-current temperature-compensated 6.9V zener reference with  
dynamic impedances a factor of 10 to 100 less than discrete diodes. Constructed in a  
single silicon chip, the LM129 uses active circuitry to buffer the internal zener allowing  
the device to operate over a 0.5 mA to 15 mA range with virtually no change in  
performance. The LM129 is available with selected temperature coefficients of 0.001,  
0.002, 0.005 and 0.01%/ C. These new references also have excellent long term stability  
and low noise.  
A new subsurface breakdown zener used in the LM129 gives lower noise and better long-term  
stability than coventional 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  
temperature cycling and the device is insenstive to stress on the leads.  
The LM129 can be used in place of conventional zeners with improved performance. The low  
dynamic impedance simplifies biasing and the wide operating current allows the replacement  
of may zener types.  
The LM129 is packaged in a 2-lead T0-46 package and is rated for operation over a -55 C to  
+125 C temperature range.
