LM431CIM3X

Voltage Reference Overview

The LM431CIM3X is a three-terminal adjustable precision Zener shunt regulator manufactured by Texas Instruments. It operates within a cathode voltage range of VREF to 37 V and supports a continuous cathode current up to 100 mA. The device features an average temperature coefficient of 50 ppm/°C and is housed in a space-saving SOT-23 package. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

Adjustable output voltage set via external resistors
Temperature compensated for stability over full operating range
Fast turn-on response characteristics

Voltage Reference Applications

Linear and switching power supplies
Voltage monitoring circuits
Current source and sink circuits
Zener diode replacements

Voltage Reference Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, tolerance grade, and environmental compliance status. Confirm that the 'X' designation corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with standard surface-mount reflow soldering profiles specified for the SOT-23 package.

Voltage Reference Selection Notes

Select this component when a compact, adjustable shunt regulator is required for space-constrained designs. Verify that the application voltage does not exceed the maximum cathode rating of 37 V. Ensure the circuit design maintains the cathode current between the minimum regulation threshold and the maximum continuous current limit to guarantee stable operation.

Voltage Reference Part Context

This part belongs to the LM431 family of adjustable precision shunt regulators from Texas Instruments. The family includes variants with different tolerance grades and package options such as SOIC-8 and TO-92. The LM431 series serves as a direct replacement for many fixed Zener diode applications requiring higher precision and programmability.
