TL1431CL3T

Overview

The TL1431CL3T is an adjustable shunt voltage reference manufactured by STMicroelectronics. It provides a stable reference voltage with guaranteed temperature stability over the operating range. The output voltage is programmable between 2.5 V and 36 V using two external resistors. The device operates within a current range of 1 mA to 100 mA, featuring a typical dynamic impedance of 0.2 Ω. Initial precision is specified at ±0.4%. It is housed in a SOT-23-3 surface-mount package.

Feature Summary

Adjustable output voltage capability ranging from 2.5 V to 36 V via external resistor network
Guaranteed temperature stability across the entire operating temperature range
Wide sink current operational range supporting applications from 1 mA to 100 mA
Low typical dynamic output impedance for effective regulation

Applications

Precision voltage references in power supply circuits
Programmable linear regulators requiring stable reference nodes
Battery-operated equipment needing accurate voltage monitoring
DC-to-DC converter feedback loops

Procurement Notes

Verify the specific suffix CL3T against official STMicroelectronics documentation to confirm the exact tolerance grade and packaging configuration. Ensure the component matches the required thermal performance specifications for the intended application environment. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a compact SOT-23-3 footprint is required for space-constrained designs. Consider the ±0.4% initial precision and temperature coefficient requirements relative to system accuracy needs. Evaluate the 1 mA minimum cathode current requirement to ensure proper operation under light load conditions within the target circuit topology.

Part Context

The TL1431CL3T belongs to the TL1431 family of shunt voltage references. This series is widely utilized in industrial and consumer electronics for its reliability and adjustability. The CL3T designation indicates a specific variant within the broader product line, tailored for surface-mount assembly processes common in modern PCB manufacturing standards.

Replacement Considerations

Compatible substitutes include the TL1431ACLT3T and TL1431CDT variants from STMicroelectronics, provided pinout compatibility and electrical parameters align with the design requirements.
