LM129/LM329
Precision Reference
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.
Anew 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.
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.
The LM129 is packaged in a 2-lead TO-46 package and is
rated for operation over a 55C to +125C temperature
range. The LM329 for operation over 0C to 70C is available
in both a hermetic TO-46 package and a TO-92 epoxy pack-
age.
