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 our in-house Class S flow to yield circuits usable in stringent military applications. * Reverse Breakdown Current: 30mA * Forward Current: 2mA * Operating Temperature Range: –55°C to 125°C
