RH129 6.9V Precision Reference UWWWUDESCRIPTIOABSOLUTEAXI UAR TI GS The RH129 precision reference features excellent stability Reverse Breakdown Current .. 30mA over a wide range of voltage, temperature and operating Forward Current... 2mA current conditions. The device achieves low dynamic Operating Temperature Range ... – 55°C to 125°C impedance by incorporating a high gain shunt regulator Storage Temperature Range ... – 65°C to 150°C around the Zener. The excellent noise performance of the Lead Temperature (Soldering, 10 sec) .. 300°C device is achieved by using a buried Zener design which eliminates surface noise usually associated with ordinary , LTC and LT are registered trademarks of Linear Technology Corporation. Zeners. The wafer lots are processed to LTC's in-house Class S flow to yield circuits usable in stringent military applica- tions.
