It operates from a 3.2V to 5.5V input rail and draws only 8.5 µA supply current, making it a fit for battery-powered instrumentation and portable sensor interfaces. The SOT-23-3 package keeps board area small, and the -40°C to 125°C temperature range covers industrial and automotive under-hood environments without derating. ## Noise floor and system accuracy Low-frequency noise is specified at 84 µVp-p. The 30 ppm/°C drift keeps the output stable across temperature. ## Package and sourcing posture","metaTitle":"REF3330AIDBZR voltage reference, 3V fixed, ±0.15%, SOT-23-3","metaDescription":"REF3330AIDBZR series voltage reference, fixed 3V output, ±0.15% tolerance, 8.5 µA supply, -40°C to 125°C, SOT-23-3.
