REF3012AIDBZR

REF3012AIDBZR is the tape-and-reel SOT-23 ordering code for the Texas Instruments REF3012 series voltage reference, listed by TI as ACTIVE. It outputs 1.250 V held between 1.2475 V and 1.2525 V (a 0.2 % initial band), with temperature drift of 35 ppm/°C typical and 75 ppm/°C maximum over -40 °C to +125 °C, and quiescent current of 42 µA typical and 50 µA maximum at 25 °C. The selection point is a low reference voltage at micropower drain: 1.25 V suits low-voltage ADC and DAC reference pins, battery monitors and threshold circuits whose rails no longer leave headroom for a 2.5 V or 3.3 V reference. Selection advice: the REF30 family shares one SOT-23 footprint across several output voltages - the 12 code is the 1.25 V member (the REF3033 also listed is the 3.3 V member), so the voltage digits in the ordering name are the critical match point, since a wrong-voltage reference shifts every conversion the design makes. Note the current datasheet (SBVS032 Rev. K) states drift as a single typical/maximum pair; older revision grading tables no longer apply. Parameters verified against the TI REF30 datasheet SBVS032 Rev. K (ordering appendix and electrical characteristics).
