TLVH431BIDBVT

Overview

The TLVH431BIDBVT 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 maximum temperature coefficient of 161 ppm/°C. It supports a cathode current range from 100 µA to 70 mA, with a maximum sink current capability of 70 mA. The component is housed in a SOT-23-5 package and is designed for surface-mount installation. It functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Adjustable output voltage setting via external resistor divider
• High precision with 0.5% initial accuracy specification
• Wide operating temperature range suitable for industrial environments
• Low power consumption with minimum operating current of 100 µA

Applications

• Battery chargers
• Switch mode power supplies
• Data acquisition systems
• Energy management circuits

Procurement Notes

Verify the specific suffix 'VT' against the official Texas Instruments datasheet to confirm the exact tape and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your region. Confirm availability status as supply chain conditions may vary. Cross-reference the pinout diagram with your PCB footprint design to ensure correct orientation and connection.

Selection Notes

Select this component when precise voltage referencing is required in space-constrained designs. The SOT-23-5 package offers a compact solution compared to larger alternatives. Consider the 0.5% accuracy and thermal stability if high precision is critical. Evaluate the 70 mA sink current limit against load requirements. Compare with standard TLV431 variants if automotive qualification or different package options are needed.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for traditional bandgap references in modern power management applications. The device integrates a reference amplifier and output transistor in a single monolithic IC. It is widely used in portable electronics and industrial control systems requiring stable voltage regulation.

Replacement Considerations

Compatible substitutes include TLVH431BIDBVR and TLVH431BIDBZT. Verify package compatibility and electrical parameter alignment before substitution. Automotive-grade variants such as TLVH431BQDBZR offer enhanced reliability but require separate validation.
