TLVH431QDBVT

Overview

The TLVH431QDBVT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 PPM/C. It supports a maximum cathode current of 70 mA and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a surface-mount SOT-23-5 configuration, it is designed for high-reliability applications requiring precise voltage referencing.

Feature Summary

Provides adjustable precision voltage reference functionality with tight initial accuracy tolerance
Supports wide operating current range suitable for diverse load conditions
Engineered for automotive-grade reliability with extended industrial temperature coverage

Applications

Automotive power supply regulation circuits
Precision voltage monitoring systems
Battery management system references

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification requirements before integration. Confirm package type matches the SOT-23-5 footprint in your design. Check current availability status as manufacturing lifecycles may vary. Ensure thermal management aligns with the specified operating temperature range during operation.

Selection Notes

Select this component when automotive reliability standards are mandatory alongside low-voltage precision requirements. Compare against standard TLVH431 variants if industrial grade suffices. Evaluate pin compatibility with existing SOT-23-5 layouts. Consider the 0.5% accuracy specification against tighter or looser budget constraints.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable shunt regulators. It serves as a high-precision alternative to traditional bandgap references. The Q-series designation typically denotes automotive qualification under AEC-Q100 standards. It complements other PMIC components in complex power distribution networks.

Replacement Considerations

Direct substitutes include TLVH431BQDBVT and TLVH431QDBVR. Verify pinout compatibility between SOT-23-5 and similar packages. Ensure electrical parameters match application requirements before substitution.
