Voltage Reference datasheet and documents for LM431BCM3-NS

LM431BCM3-NS

Voltage Reference Overview

The LM431BCM3-NS is a three-terminal adjustable precision Zener shunt regulator manufactured by National Semiconductor. It features an output voltage range from 2.495 V to 37 V with an initial accuracy of ±1%. The device operates with a maximum series reference input voltage of 37 V and supports a maximum shunt current of 100 mA. It exhibits a temperature coefficient of 50 ppm/°C and functions within a junction temperature range of -25°C to 85°C. Packaged in a TO-92-3 through-hole case, it serves as a stable voltage reference component.

Voltage Reference Feature Summary

Three-terminal adjustable shunt regulator design
Guaranteed temperature stability across operating range
High initial accuracy specification

Voltage Reference Applications

Precision voltage references
Programmable linear regulators
Voltage monitoring circuits

Voltage Reference Procurement Notes

Verify the manufacturer designation 'NS' corresponds to National Semiconductor legacy production. Confirm package integrity for the TO-92-3 form factor. Ensure compatibility with thermal requirements given the specified junction temperature limits. Cross-reference datasheet specifications against current inventory documentation to validate performance parameters before integration.

Voltage Reference Selection Notes

Select this component when a low-cost, through-hole adjustable shunt regulator is required. The ±1% accuracy suits applications needing moderate precision. Consider the 100 mA current capability for load driving needs. Evaluate the TO-92-3 package for board space constraints compared to surface-mount alternatives.

Voltage Reference Part Context

This part belongs to the LM431 family of adjustable precision Zener shunt regulators. It shares functional similarities with other variants like the LM431ACZ but differs in package type and specific accuracy grades. The National Semiconductor branding indicates its origin prior to the Texas Instruments acquisition era.
