Product details

Fixed 3 V series reference in SOT-23-3

The REF3030AIDBZRG4: It delivers up to 25 mA output current while drawing only 50 µA quiescent supply current — the low self-heating keeps the reference stable even when driving an ADC reference input or a small load.

±0.2% tolerance and 75 ppm/°C drift

Initial output accuracy is ±0.2%, which for a 3 V reference means the output is within 6 mV of nominal at 25°C. Noise is specified at 33 µVp-p from 0.1 Hz to 10 Hz and 94 µVrms from 10 Hz to 10 kHz, both measured without external filtering.

The SOT-23-3 package (also listed as TO-236-3 / SC-59) is a three-pin surface-mount footprint that shares the same land pattern across many standard voltage references, easing second-source qualification.

Frequently asked questions

What is the tolerance of REF3030AIDBZRG4?

Initial output tolerance is ±0.2%, which translates to a 6 mV window around 3 V at 25°C.
