TLVH431BIDCKRE4

Overview

The TLVH431BIDCKRE4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 18 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy tolerance of ±0.5% and supports a maximum cathode current of 70 mA with a minimum operating current of 100 µA. It is housed in a compact SC-70-6 surface-mount package and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Adjustable reference voltage capability spanning from 1.24 V to 18 V for flexible circuit design
• High initial accuracy of ±0.5% ensures precise voltage regulation performance
• Low minimum operating current requirement facilitates efficient power management in battery-powered applications

Applications

• Portable consumer electronics requiring stable low-voltage references
• Battery-operated devices needing efficient power supply monitoring
• General-purpose analog signal conditioning circuits

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS standards during procurement. Confirm that the SC-70-6 package matches your PCB footprint requirements. Ensure the ±0.5% accuracy grade meets your system's precision specifications before finalizing component selection.

Selection Notes

Select this component when a low-voltage, high-accuracy shunt regulator is required in a small form factor. The SC-70-6 package offers space savings compared to larger alternatives. Consider the 70 mA current limit and 18 V maximum voltage to ensure compatibility with your circuit's operational parameters.

Part Context

This part belongs to the TLVH431 series of low-voltage adjustable precision shunt regulators. It serves as a drop-in replacement for standard TL431 devices in low-voltage applications, offering improved performance characteristics such as lower minimum operating current and tighter accuracy tolerances within a compact surface-mount package.

Replacement Considerations

The TLVH431BIDCKR is the primary equivalent without the E4 suffix. Verify if the packaging or environmental compliance differences affect your assembly process.
