RH129
6.9V Precision Reference
DESCRIPTIO
The RH129 precision reference features excellent stability
over a wide range of voltage, temperature and operating
current conditions. 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 usually associated with ordinary
Zeners.
The wafer lots are processed to LTC's in-house Class S
flow to yield circuits usable in stringent military applica-
tions.
