TLV431BQLPR

Overview

The TLV431BQLPR is a low-voltage, adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a maximum input voltage of 7 V and provides an adjustable output voltage up to 6 V. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 ppm/°C. It supports a maximum shunt current of 15 mA with a minimum operating current of 80 uA. The component functions across a temperature range from -40°C to +125°C and is housed in a TO-92-3 through-hole package.

Feature Summary

Provides adjustable reference voltage functionality suitable for low-voltage applications
Offers high precision with specified initial accuracy and thermal stability
Features active output circuitry for sharp turn-on characteristics

Applications

Secondary side regulation in flyback switch-mode power supplies
Isolated feedback circuits for 3V to 3.3V SMPS when used with optocouplers
Adjustable voltage and current references
Zener diode replacement in board-level regulation

Procurement Notes

Verify the specific suffix 'QLP' against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status via the manufacturer's datasheet or environmental files. Check for product discontinuance notifications as this series may have end-of-life variants. Ensure the ordering part number matches the required accuracy and thermal specifications before procurement.

Selection Notes

Select this component for applications requiring low-voltage operation where standard TL431 devices exceed the supply voltage limit. The TO-92-3 package is suitable for through-hole mounting requirements. Consider the 138 ppm/°C temperature coefficient for thermal stability needs. Verify that the 15 mA maximum shunt current meets the load requirements of the specific circuit design.

Part Context

This device belongs to the TLV431 family of low-voltage adjustable precision shunt regulators. It serves as a lower-voltage alternative to the widely used TL431 and TL1431 series. The TLV431 family is designed to operate with lower input voltages, making it ideal for modern low-voltage power management systems and isolated feedback loops.
