It operates as a shunt (two-terminal) reference, meaning it sinks current through an external resistor to set the output voltage — no separate supply pin needed. The 50 ppm/°C temperature coefficient keeps the reference stable across the -40°C to 85°C industrial temperature range, making it a fit for precision analog circuits like ADC reference buffers, comparator thresholds, and bias generators in sensor interfaces or power-supply monitoring. ## Output range and load — what the ratings mean for your BOM The adjustable output from 1.212 V (the internal bandgap) to 10 V means a single resistor pair sets the reference voltage — no need to stock multiple fixed-voltage references. The 12 mA output current capability is the maximum the shunt can sink; for driving a typical ADC reference input (drawing microamps), that headroom is generous, but if you are paralleling several loads or driving a long trace, keep the total cathode current under 12 mA. The 65 µA minimum cathode current is the floor — below that the reference may drop out of regulation, so size the bias resistor to guarantee at least 65 µA through the device at all line and load conditions. ## Package and mounting for production The SOT-23-3 (TO-236-3, SC-59) surface-mount package is a standard footprint for small-signal devices — same land pattern as many shunt references and small transistors. The Tape & Reel or Cut Tape options suit both prototype builds and volume reflow. No special handling beyond standard SMT assembly; the -40°C to 85°C operating range covers most indoor and outdoor telecom, industrial control, and automotive cabin environments.","metaTitle":"TL4051BIDBZT Shunt Voltage Reference","metaDescription":"TL4051BIDBZT adjustable shunt voltage reference from Texas Instruments.
