2.5 V reference with ±0.2% initial accuracy — the tolerance that sets the ADC floor
That tolerance is the first thing to check when this part lands on a BOM — it sets the voltage accuracy budget for the ADC reference input or the comparator threshold. If the system needs better than ±5 mV at 2.5 V without trimming, this part holds that line out of the tube.
50 µA quiescent — the power budget spec that matters for always-on rails
Supply current is 50 µA typical. For a reference that stays powered continuously — battery monitors, always-on sensor bias, supervisory circuits — that 50 µA is a fixed overhead on the system power budget. It draws less than the leakage of many low-dropout regulators at high temperature, so it is a clean fit for a low-power rail that cannot afford a milliampere-class reference.
