TLV431AIDBVR

Overview

The TLV431AIDBVR is a shunt adjustable precision voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of up to 7 V and provides an adjustable output voltage up to 6 V. The device features an initial accuracy of 1% and a temperature coefficient of 138 PPM/°C. It supports a maximum shunt current of 15 mA with a minimum operating current of 80 µA. The component functions across a wide temperature range from -40°C to +125°C and is housed in a SOT-23-5 surface-mount package.

Feature Summary

• Provides stable, adjustable reference voltage for precision applications
• Operates over extended industrial temperature ranges
• Designed for low-cost power management circuits

Applications

• Portable equipment power supplies
• DC-to-DC converters
• Battery chargers
• Process control systems

Procurement Notes

Verify the specific suffix 'DBVR' confirms the SOT-23-5 package and reel packaging format. Ensure the 'A' grade designation matches the required 1% initial accuracy specification. Confirm RoHS compliance status through official manufacturer documentation before procurement.

Selection Notes

Select this component when a low-cost, adjustable shunt reference is required for feedback loops in switching regulators. Consider the 138 PPM/°C temperature coefficient for thermal stability requirements. Verify that the 15 mA maximum cathode current meets the load regulation needs of the target circuit design.

Part Context

This part belongs to the TLV431 family of programmable shunt voltage references. It serves as a cost-effective alternative to Zener diodes in regulation and protection circuits. The device integrates a 1.24 V internal reference with error amplifier functionality.
