DESCRIPTIO

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.
