TL1431CLPR

Overview

The TL1431CLPR is a precision programmable shunt voltage reference manufactured by Texas Instruments. It features an initial voltage tolerance of 0.4% and operates with a cathode current range from 1 mA to 100 mA. The output voltage is adjustable between approximately 2.5 V and 36 V using two external resistors. This device is characterized for commercial temperature operation from 0°C to 70°C and is housed in a TO-92 (LP) package.

Feature Summary

Provides precise voltage referencing with specified thermal stability across the operating temperature range.
Features fast turn-on characteristics suitable for Zener diode replacement applications.
Internally compensated for stability without requiring an output capacitor between cathode and anode.

Applications

Adjustable voltage and current referencing
Secondary side regulation in flyback switch-mode power supplies
Voltage monitoring circuits
Comparator applications with integrated reference

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the TL1431 family includes various packages such as SOIC, TSSOP, CDIP, and LCCC. Confirm the temperature grade corresponds to the application environment, ensuring the 'C' suffix aligns with commercial requirements rather than automotive or military grades.

Selection Notes

Select this component when a high-precision shunt regulator with low dynamic impedance is required. Ensure the design maintains a minimum cathode current of 1 mA for proper regulation. Consider the thermal resistance metrics if operating near maximum load conditions within the commercial temperature range.

Part Context

The TL1431 series serves as a versatile analog building block combining an accurate voltage reference and an operational amplifier. It functions as a single voltage reference, error amplifier, or comparator. The device is widely used in industrial, automotive, telecom, and computing equipment due to its wide operating voltage range and robust performance.
