General DescriptionThe LM129 and LM329 family are precision multi-current
temperature-compensated 6.9V zener references with dy-
namic impedancesa factorof10to 100 less than discretedi-
odes. Constructedina single silicon chip, the LM129 uses
active circuitryto buffer the internal zener allowing the de-
viceto operate overa0.5 mAto15 mA range with virtually changein performance. The LM129 and LM329 are avail-
able with selected temperature coefficientsof 0.001, 0.002,
0.005 and 0.01%/˚C. These references also have excellent
long term stability and low noise. new subsurface breakdown zener usedin theLM129 gives
lower noise and better long-term stability than conventional zeners. Furtherthe zener and temperature compensating
transistor are madebya planar processso they are immune problems that plague ordinary zeners. For example, there virtuallyno voltage shiftin zener voltage dueto tempera-
ture cycling and the deviceis insensitiveto stresson the
leads.
The LM129 canbe usedin placeof conventional zeners with
improved performance. The low dynamic impedance simpli-
fies biasing and the wide operating current allows there-
placementof many zener types.
The LM129is packagedina 2-lead TO-46 package andis
ratedfor operation overa −55˚Cto +125˚C temperature
range. The LM329for operation over 0˚Cto 70˚Cis available botha hermetic TO-46 package anda TO-92 epoxy pack-
age.
Features 0.6 mAto15 mA operating current 0.6Ω dynamic impedanceat any current Available with temperature coefficientsof 0.001%/˚C 7μV wideband noise 5% initial tolerance 0.002% long term stability Low cost Subsurface zener
