It delivers a programmable output from 2.5 V up to 36 V with a tight ±0.4% initial tolerance, and can sink up to 100 mA. The shunt topology means it behaves as a three-terminal programmable Zener — no external pass transistor needed for moderate loads, just a single resistor from the supply rail.
The 8-SOIC package is a common footprint, so it cross-references to many standard shunt references if a second source is needed — but the military temperature range and ±0.4% tolerance make this the tighter-spec option for harsh-environment designs.
