TL431QDCKR

Overview

The TL431QDCKR is a programmable shunt regulator from Texas Instruments, housed in an SC-70-6 surface-mount package. It provides an adjustable output voltage range from 2.495 V to 36 V. The device features an initial accuracy of ±2.2% and supports a maximum cathode current of 100 mA. It operates within a temperature range of -40°C to +125°C.

Feature Summary

Programmable reference voltage adjustable between 2.495 V and 36 V via external resistors
Automotive-grade qualification with specified thermal stability for harsh environments
Low dynamic output impedance ensuring stable regulation under varying load conditions

Applications

Precision voltage references in automotive electronic control units
Power supply feedback loops requiring high stability
Portable equipment power management circuits

Procurement Notes

Verify the specific suffix 'DCKR' corresponds to the SC-70-6 package and tape-and-reel configuration. Confirm RoHS compliance status and ensure the ±2.2% tolerance meets system requirements. Check for any recent PCN notices regarding marking or design changes that may affect integration.

Selection Notes

Select this component when automotive reliability and compact SMD packaging are required. Compare against TL431BQDCKR if tighter ±0.5% accuracy is needed. Ensure the 100 mA sink capability aligns with the circuit's current demands and that the SC-70-6 footprint fits the PCB layout constraints.

Part Context

This part belongs to the TL431 family of three-terminal adjustable shunt regulators. It shares functional similarities with other TL431 variants but is distinguished by its automotive qualification level and specific SC-70-6 form factor designed for space-constrained applications.

Replacement Considerations

TL431BQDCKRG4 offers higher precision at ±0.5% accuracy in the same package. TL431QDCKRE4 is an alternative variant within the same qualification class.
