The series topology means the load current comes from the input supply, not a buried-zener shunt — the part draws only 50 µA quiescent current, making it viable for battery-powered and always-on rails where every microamp counts. ## Noise floor and temperature drift — the real-world limits Output noise is specified at 33 µVp-p over 0.1 Hz to 10 Hz and 94 µVrms over 10 Hz to 10 kHz. For a 3 V reference, that 33 µVp-p is about 11 ppm of the output — clean enough for a 16-bit SAR ADC with a 3 V reference input, where the reference noise contribution stays below 1 LSB. Temperature coefficient is 75 ppm/°C. ## 25 mA output — enough for a reference, not a regulator Rated for 25 mA output current, this part can drive the reference input of multiple ADCs or a small load, but it is not a power supply — drawing near the limit raises the junction temperature and shifts the output. Keep the load under 10 mA for best stability. ## SOT-23-3 package and tape-and-reel delivery","metaTitle":"REF3030AIDBZTG4 Voltage Reference, 3V Fixed ±0.2%, SOT-23-3","metaDescription":"Texas Instruments REF3030AIDBZTG4 series voltage reference, fixed 3V output, ±0.2% tolerance, 25 mA output, 33µVp-p noise.
