REF3033AIDBZR

REF3033AIDBZR is the tape-and-reel SOT-23 ordering code for the Texas Instruments REF3033 series voltage reference, listed by TI as Active. It outputs 3.300 V held between 3.294 V and 3.306 V, with temperature drift of 35 ppm/°C typical and 75 ppm/°C maximum over -40 °C to +125 °C, quiescent current of 42 µA typical and 50 µA maximum at 25 °C, and a maximum output current of 25 mA. The selection point is a precision reference that behaves like a low-power regulator: ADC and DAC reference pins, sensor excitation and threshold setting get a stable 3.3 V anchor that draws less current than the circuits it feeds in battery-powered measurement equipment. Selection advice: the REF30 family spans several output voltages under one footprint - the 33 code is the 3.3 V member, so match the voltage digits in the ordering name to the reference the design was calibrated against; and keep load current inside the 25 mA ceiling, buffering the output if the reference must also drive dynamic loads. Parameters verified against the TI REF30 datasheet SBVS032 Rev. K (ordering appendix and electrical characteristics).
