TLVH431ACDCKR

Overview

The TLVH431ACDCKR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.5 V to 36 V and features an initial accuracy of ±1%. The device supports a wide operating current range from 100 µA to 100 mA, enabling efficient performance across varying load conditions. It is housed in a compact SC-70-6 package and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Adjustable output voltage capability spanning 2.5 V to 36 V
• High initial accuracy of ±1% for precise reference applications
• Wide operating current range supporting loads from 100 µA to 100 mA

Applications

• Precision voltage references in portable electronics
• Battery-powered measurement instruments
• Low-voltage power supply regulation circuits

Procurement Notes

Verify the specific suffix 'A' indicates the ±1% accuracy grade and 'CDK' denotes the SC-70-6 package configuration. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation for automotive or industrial qualification requirements if applicable.

Selection Notes

Select this component when a low-voltage shunt regulator with high initial accuracy is required. Ensure the application voltage does not exceed the 36 V maximum rating. Consider the thermal characteristics of the SC-70-6 package for heat dissipation needs in dense PCB layouts.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for standard TL431 devices in low-voltage applications, offering improved performance at lower supply voltages while maintaining similar functionality and pinout compatibility.

Replacement Considerations

Direct substitutes include other manufacturers' low-voltage shunt regulators with matching accuracy and package dimensions. Verify that alternative parts support the same 100 µA minimum cathode current and 36 V maximum voltage rating.
