Output current is rated for 25 mA, enough to bias a handful of op-amp stages or a single ADC reference input without a buffer. The 50 µA quiescent supply current keeps the thermal load negligible in a battery-powered node. ## Input headroom and package fit Input voltage range is 3.35 V to 5.5 V. The SOT-23-3 package (TO-236-3, SC-59) is shared across the REF30xx family.","metaTitle":"REF3033AIDBZTG4 3.3V Series Voltage Reference, ±0.2%","metaDescription":"Texas Instruments REF3033AIDBZTG4: fixed 3.3V output, ±0.2% tolerance, 75ppm/°C drift, 36µVp-p noise.
