REF3030AIDBZR

REF3030AIDBZR is the AI accuracy grade of a fixed 3.0 V series voltage reference in a SOT-23-3 (DBZ) package, with +/-0.2% initial accuracy. It supplies up to 25 mA of output current, accepts a 3.05 V to 5.5 V input, draws a typical 42 µA, and operates from -40 C to +125 C. A stable 3.0 V reference improves ADC and DAC measurement repeatability in sensor interfaces, portable instruments and data-acquisition front ends, and the 25 mA output can also bias small analog loads directly, removing a separate buffer in simple designs. Selection advice: the AI grade is the tighter-accuracy order option, so confirm the full AIDBZR code rather than a lower grade when the error budget depends on it; also verify the reference voltage your converter expects, because this code is fixed at 3.0 V and the family offers other fixed output voltages under different codes. Parameters verified against Texas Instruments documentation.
