TLVH431AIDCKT

Overview

The TLVH431AIDCKT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V and provides an initial accuracy of 1.5%. The device supports a maximum cathode current of 70 mA with a minimum operating current of 100 µA. It features a temperature coefficient of 161 ppm/°C and withstands a maximum reference input voltage of 20 V. The component functions reliably across a temperature range from -40°C to +125°C and is housed in a SC-70-6 surface-mount package.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 18 V via external resistor dividers
• Precision regulation performance with guaranteed initial accuracy specifications
• Extended thermal stability ensuring reliable operation across wide industrial temperature ranges

Applications

• Battery-operated equipment requiring low power consumption
• Switch mode power supplies for voltage regulation
• Data acquisition systems needing stable reference voltages
• Battery chargers utilizing precise shunt regulation

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SC-70-6 package dimensions match your PCB footprint requirements. Ensure the 1.5% accuracy grade meets your circuit tolerance needs. Check for any recent Product Change Notifications regarding marking or packaging updates before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for adjustable voltage referencing. The SC-70-6 package offers space efficiency compared to larger through-hole alternatives. Consider the 70 mA sink current capability against your load requirements. Verify that the 1.5% accuracy aligns with your system's precision constraints rather than opting for higher-grade variants if cost is a factor.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable shunt regulators designed for space-constrained applications. It serves as a modern alternative to traditional three-terminal references, offering improved performance in small packages. The series supports various accuracy grades and package options to suit diverse design requirements while maintaining compatibility with standard control loop architectures.

Replacement Considerations

TLVH431QDCKT: Automotive qualified version with similar electrical characteristics. TLVH431BIDCKR: Higher accuracy variant (0.5%) in the same package. STMicroelectronics TLVH431AIL3T: Compatible pinout and function from alternate supplier.
