TYPICAL APPLICATION
DESCRIPTION
6.9V Precision
Voltage Reference
The LM129 temperature compensated 6.9V Zener refer-
ences provide excellent stability over time and temperature,
very low dynamic impedance and a wide operating current
range. The device achieves low dynamic impedance by
incorporating a high gain shunt regulator around the Zener.
The excellent noise performance of the device is achieved
by using a “buried Zener” design which eliminates surface
noise phenomenon associated with ordinary Zeners. To
serve a wide variety of applications, the LM129 is available
in several temperature coefcient grades and two pack-
age styles. A 20mA positive current source application is
shown below.
