Initial output tolerance is ±0.05%, and the temperature coefficient is 30 ppm/°C. Input voltage range is 3.05 V to 5.5 V. Output current is rated for 10 mA. Supply current is 100 µA typical — a low quiescent draw that matters in always-on automotive modules where every microamp counts against the sleep-mode budget. ## Package and mounting The SOT-23-5 footprint is forgiving; you can hand-solder a replacement with fine tweezers. ## Lifecycle and sourcing This part is listed as Active and ROHS3 Compliant. No end-of-life notice or last-time-buy window has been issued.","metaTitle":"REF4132B30DBVRQ1 Voltage Reference, 3V ±0.05%, AEC-Q100","metaDescription":"TI REF4132B30DBVRQ1 series voltage reference, 3V fixed output, ±0.05% tolerance, 30ppm/°C drift, 15µVp-p noise, AEC-Q100, SOT-23-5.
