TL1431QDREP

Overview

The TL1431QDREP is a military-enhanced, adjustable shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 36 V and supports a sink current capability from 1 mA to 100 mA. The device features an initial accuracy of 0.4% and a temperature coefficient of 114 PPM/°C. It is housed in an SOIC-8 surface-mount package and is rated for operation between -55°C and +125°C. The maximum series input voltage is 37 V.

Feature Summary

Military-grade enhanced precision with guaranteed temperature stability across the full operating range
Adjustable output voltage settable via two external resistors
Wide operating current range supporting low-power and high-current applications

Applications

Precision power supply regulation
Battery-operated equipment monitoring
Over-voltage protection circuits

Procurement Notes

Verify the specific suffix 'REP' against the manufacturer's official datasheet to confirm military qualification status and exact electrical tolerances. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm RoHS compliance details as listed in the official documentation before finalizing procurement specifications.

Selection Notes

Select this component when military-grade reliability and wide temperature operation are required. The adjustable nature allows flexibility in setting reference voltages. Compare the 0.4% initial accuracy against standard commercial variants if cost is a primary constraint. Ensure the 100 mA sink current meets the circuit's load requirements.

Part Context

This part belongs to the TL1431 family of adjustable shunt references. It shares functional similarities with the TL431 but offers enhanced performance characteristics suitable for demanding environments. The QDREP designation indicates a specific military-grade variant within the broader Texas Instruments voltage reference portfolio.
