It is designed for applications that need a stable, low-noise voltage rail — think ADC references, sensor excitation, or power-supply monitoring in industrial or automotive environments. The ±0.15% initial tolerance and 30 ppm/°C temperature coefficient keep the output tight across the -40°C to 125°C operating range, so the reference holds its accuracy whether the board sits in a cold warehouse or near a motor drive. Supply current is 8.5 µA typical, which matters for loops that cannot spare much quiescent draw. ## Input range and output drive Input voltage range is 3.5 V to 5.5 V. Output current is rated at 5 mA. ## Package and mounting Housed in a SOT-23-3 package (also listed as TO-236-3 / SC-59), this is a three-pin surface-mount device. The small footprint suits dense PCBs, but the limited pin count means no trim or shutdown function — the output is always on when the input is present. ## Lifecycle and sourcing The part is ROHS3 compliant. For current availability and pricing, submit an RFQ — the supply position is confirmed at quote time through independent distribution.","metaTitle":"REF3333AIDBZR 3.3V Series Voltage Reference, ±0.15%","metaDescription":"TI REF3333AIDBZR precision 3.3V series voltage reference. ±0.15% tolerance, 30ppm/°C drift, 8.5µA supply.
