TL1431IDT ST Voltage References

The TL1431IDT is a programmable precision shunt voltage reference from STMicroelectronics in SO-8 package, offering output voltage from 2.5V to 36V with tight tolerance. For selection, verify output voltage programmable with two external resistors from 2.5V to 36V, sink current capability, output impedance of 0.2Ω typical, temperature coefficient, and operating temperature from -40°C to +105°C (industrial grade). Features include excellent thermal stability, low dynamic output impedance, low output noise, and AEC-Q100 qualification for automotive applications. Ideal for switch-mode power supply feedback (opto-coupler drivers), precision voltage references for ADCs/DACs, shunt regulators replacing zener diodes, overvoltage protection circuits, constant current sources/sinks, and low-cost adjustable power supplies in industrial control, battery chargers, and consumer electronics requiring up to 36V programmable output.
