TL431BVLP

Overview

The TL431BVLP is a three-terminal programmable shunt regulator from onsemi, operating within an ambient temperature range of -40°C to +125°C. It features a reference voltage tolerance of ±0.4% at 25°C and a typical dynamic output impedance of 0.14 Ω. The device supports a cathode current range of 1.0 mA to 100 mA with a maximum cathode-to-anode voltage of 36 V. Packaged in the TO-92 (TO-226) LP suffix configuration, it provides low output noise and temperature compensation for stable operation across its rated range.

Feature Summary

Programmable output voltage adjustable from the internal reference up to 36 V using external resistors
Temperature compensated for reliable operation over the full industrial and extended temperature range
Low dynamic output impedance ensuring stable regulation under varying load conditions

Applications

Shunt regulators in power supply circuits
Voltage monitoring systems requiring precise threshold detection
Feedback control loops driving optocouplers in isolated converters

Procurement Notes

Verify that the specific order includes the BV suffix to confirm the extended -40°C to +125°C operating temperature range. Ensure the LP package code matches the required TO-92 form factor. Confirm RoHS compliance status if halogen-free requirements are mandatory for the assembly process.

Selection Notes

Select this component when high precision is required alongside wide thermal stability. The B grade offers tighter voltage tolerance compared to standard variants. Consider the TO-92 package constraints regarding power dissipation and mounting orientation relative to the circuit board layout.

Part Context

This device belongs to the TL431 family of programmable precision references manufactured by onsemi. It serves as a direct replacement for traditional Zener diodes in applications demanding higher accuracy and lower temperature drift. The family includes various grades and packages tailored for different automotive and industrial environments.
