TL431BCLPRE3

Overview

The TL431BCLPRE3 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and provides an initial accuracy of 0.5%. The device supports a maximum cathode current of 100 mA and maintains a temperature coefficient of 92 PPM/°C. It functions reliably across an operating temperature range from -40 °C to +125 °C. The component is housed in a TO-92-3 through-hole package.

Feature Summary

Provides high-precision voltage regulation with 0.5% initial accuracy for stable reference applications.
Capable of handling up to 100 mA cathode current for robust shunt regulation performance.
Designed for extended industrial environments with operation supported from -40 °C to +125 °C.

Applications

Precision voltage references in power supply circuits
Programmable output regulators
Voltage monitoring and protection circuits

Procurement Notes

Verify the specific suffix 'PRE3' against official Texas Instruments documentation to confirm RoHS compliance and lead-free status. Confirm that the TO-92-3 package matches your PCB footprint requirements. Ensure the 0.5% accuracy grade meets your design specifications, as other grades like CL or AC offer different tolerances.

Selection Notes

Select this component when high accuracy (0.5%) is required alongside wide temperature stability. The TO-92-3 package suits through-hole designs. Compare against TL431ACLP or TL431CLP if lower accuracy or automotive ratings are acceptable. Verify input voltage limits do not exceed 36 V in your specific circuit topology.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. These devices function similarly to Zener diodes but offer adjustable output voltages via external resistors. The TL431 series is widely used in feedback loops for switching power supplies and linear regulators due to its reliability and precision.
