TL1431CD

Overview

The TL1431CD is an adjustable shunt voltage reference manufactured by STMicroelectronics, housed in an 8-pin SOIC surface-mount package. It provides a programmable output voltage range from 2.5 V to 36 V using two external resistors. The device features an initial accuracy of 0.4% and operates with a sink current capability between 1 mA and 100 mA. It supports a maximum input voltage of 37 V and maintains stability across a commercial temperature range of -20 °C to +70 °C.

Feature Summary

Adjustable output voltage settable between 2.5 V and 36 V via external resistors
High precision with 0.4% initial accuracy tolerance
Wide operating current range supporting 1 mA to 100 mA sink currents

Applications

Precision voltage regulation in power supply circuits
Programmable power control systems
Battery-operated equipment requiring stable reference voltages

Procurement Notes

Verify the specific suffix 'CD' against the manufacturer's official datasheet to confirm the exact temperature grade and package variant. Ensure compatibility with the required operating environment, as this part is specified for commercial temperatures. Cross-reference pinouts and electrical limits with the latest STMicroelectronics documentation before finalizing procurement specifications.

Selection Notes

Select the TL1431CD when a compact surface-mount solution is required for adjustable voltage referencing. Its 0.4% accuracy suits applications demanding tighter tolerances than standard references. Consider the 8-SOIC footprint for PCB space constraints and verify that the commercial temperature range meets the system's operational requirements.

Part Context

This component belongs to the TL1431 family of programmable shunt voltage references. These devices are widely used as precise voltage references in linear regulators, switching converters, and battery chargers. The TL1431 series offers a cost-effective alternative to Zener diodes with superior temperature stability and lower dynamic impedance characteristics.

Replacement Considerations

Direct replacements include the TL1431IDT for extended industrial temperature ranges or the TL1431ACD for higher precision variants. Verify pinout compatibility and thermal performance when substituting.
