REF3020AIDBZR

REF3020AIDBZR is a Texas Instruments series voltage reference in a SOT-23-3 package, delivering a fixed 2.048 V output with 0.2% maximum initial accuracy and 75 ppm/°C maximum temperature drift. It draws 42 µA typical quiescent current, sources up to 25 mA, and runs from supplies up to 5.5 V over −40 to +125 °C — the low-power reference for battery instruments, data-acquisition front ends and precision bias points. Selection advice: the 2.048 V value is the binary-friendly step of the REF30 family, whose 2.5 V, 3.0 V, 3.3 V and 4.096 V siblings share the footprint and the DBZR reel code — pick the voltage your ADC full scale actually wants, since a reference change rescales every measurement; the A in the code is the 0.2% initial-accuracy grade. TI lists this code as Active (Production). Parameters verified against Texas Instruments documentation.
