LM431CIZ

Voltage Reference Overview

The LM431CIZ is a shunt adjustable voltage reference manufactured by Texas Instruments, not onsemi. It features an output voltage range of 2.495 V to 37 V with an initial accuracy of 0.5%. The device operates within a temperature range of -40°C to +85°C and has a maximum shunt current of 100 mA. It utilizes a TO-92-3 through-hole package. The component is listed as obsolete or discontinued in public records.

Voltage Reference Feature Summary

Adjustable precision Zener shunt regulator functionality
High initial accuracy for stable reference applications
Through-hole mounting capability

Voltage Reference Applications

Precision voltage regulation circuits
Power supply feedback loops
Battery charging control systems

Voltage Reference Procurement Notes

Verify manufacturer details carefully as the LM431CIZ is produced by Texas Instruments. Confirm availability status as the part may be discontinued. Check RoHS compliance markings on physical units. Ensure correct pinout identification for TO-92-3 packages during integration.

Voltage Reference Selection Notes

Select this component when through-hole mounting is required for adjustable shunt references. Consider the 0.5% initial accuracy specification for precision requirements. Evaluate thermal performance within the specified operating temperature range. Verify compatibility with circuit input voltage limits up to 37 V.

Voltage Reference Part Context

This component belongs to the LM431 family of adjustable shunt regulators. It serves as a low-cost alternative to fixed voltage references. The TO-92-3 package distinguishes it from surface-mount variants like SOT-23-3. It is widely used in industrial and consumer electronics for voltage monitoring and regulation tasks.
