Housed in a SOT-23-3 package, it is designed for surface-mount assembly and operates over the industrial temperature range of -40°C to 85°C. Typical applications include precision data converters, battery-powered instrumentation, and portable test equipment where a stable, low-noise reference voltage is needed. As a shunt reference, it behaves like a Zener diode — it requires an external series resistor to bias the cathode current, which is set at 80 µA typical. The output current capability is 15 mA, sufficient to drive the reference input of most ADCs and DACs without additional buffering. ## Lifecycle and compliance It is ROHS3 Compliant, meeting the latest EU restriction directive. The SOT-23-3 package is widely second-sourced, so supply continuity is good.","metaTitle":"TL4050A50IDBZT Shunt Voltage Reference, 5V ±0.1% SOT-23-3","metaDescription":"TI TL4050A50IDBZT precision shunt voltage reference, fixed 5V output, ±0.1% tolerance, 50 ppm/°C drift, SOT-23-3.
