A very stable and low noise linear voltage regulator for nuclear applications

We have realized a new instrument to equip an array of large mass bolometers. The instrument is a linear bipolar supply voltage having very stringent specifications. It has a large power supply rejection ratio, in excess of 100 dB, a low noise and a negligible drift, less than 2 ppm//spl deg/C. Its outputs can be selected in the range starting from /spl plusmn/5 V up to /spl plusmn/12 V with a maximum load current of 2 A.
