Housed in a standard SOT-23-3 surface-mount package (also known as TO-236-3 or SC-59), it occupies minimal board area and shares the same footprint as many general-purpose references, simplifying layout reuse. ## Noise, drift, and operating range Output noise is specified at 20 µVrms over a 10 Hz to 10 kHz bandwidth — low enough that in a 12-bit system with a 1.225 V full-scale, the reference noise contributes less than 1 LSB of uncertainty. As a shunt reference, it sinks a cathode current of 65 µA minimum and can source up to 12 mA to the load — the low minimum bias current makes it suitable for battery-powered designs where every microamp counts.","metaTitle":"TL4051A12IDBZT Texas Instruments Shunt Reference","metaDescription":"Texas Instruments TL4051A12IDBZT precision shunt voltage reference, 1.225V fixed output, ±0.1% tolerance, SOT-23-3.
