RH129 Datasheet | Linear Technology

RH129 6.9V Precision Reference DESCRIPTIO ABSOLUTE AXI U RATI GS 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 applications.
