Voltage Reference
The LM129 temperature compensated 6.9V zener refer-
ences provide excellent stability over time and tempera-
ture, very low dynamic impedance and a wide operating
current range. The device achieves low dynamic imped-
ance 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 elimi-
nates surface noise phenomenon associated with ordi-
nary zeners. To serve a wide variety of applications, the
LM129 is available in several temperature coefficient
grades and two package styles. A 20mA positive current
source application is shown below.
