TLVH431QDBVTG4

Overview

The TLVH431QDBVTG4 is a low-voltage adjustable precision shunt regulator from the TLVH431Q automotive series. It operates within a reference voltage range of 1.24 V to 18 V and provides an initial accuracy of 0.5%. The device supports a maximum cathode current of 80 mA and withstands a maximum input voltage of 20 V. It functions reliably across an extended temperature range from -40 °C to +125 °C. The component is housed in a surface-mount SOT-23-5 package.

Feature Summary

• Automotive-grade qualification for reliable operation in vehicle environments
• Adjustable output voltage capability with high precision
• Extended thermal stability for harsh operating conditions

Applications

• Automotive power supply regulation
• Voltage reference circuits in vehicle electronics
• Battery management systems

Procurement Notes

Verify the specific suffix DBVTG4 against the official Texas Instruments datasheet to confirm the exact package type, tape-and-reel specifications, and RoHS compliance status. Ensure the part number matches the intended automotive grade requirements before procurement.

Selection Notes

Select this component when automotive reliability standards are mandatory. The 0.5% accuracy suits applications requiring tight voltage tolerance. Verify that the 80 mA cathode current meets the load requirements and that the SOT-23-5 footprint fits the design constraints.

Part Context

This part belongs to the TLVH431Q family, which is designed specifically for automotive applications. It serves as a three-terminal shunt regulator, offering a cost-effective alternative to series regulators in space-constrained designs where precise voltage referencing is critical.

Replacement Considerations

Check for direct equivalents within the TLVH431Q or TLV431 families. Confirm pin compatibility and electrical parameter alignment before substitution.
