Voltage Reference datasheet and documents for LM431CCM3

LM431CCM3

Voltage Reference Overview

The LM431CCM3 is a three-terminal adjustable precision Zener shunt regulator manufactured by Texas Instruments. It operates in the SOT-23 package and provides temperature-compensated performance across the commercial range of 0°C to 70°C. The device features an internal reference voltage with a typical value of 2.495 V, allowing output voltages to be set between 2.5 V and 36 V using two external resistors. It exhibits a low average temperature coefficient of 50 ppm/°C and supports cathode currents from 1 mA to 100 mA.

Voltage Reference Feature Summary

Temperature compensated for operation over the full commercial temperature range
Fast turn-on response characteristics suitable for linear and switching power supplies
Low dynamic output impedance and low-output noise performance

Voltage Reference Applications

Adjustable voltage or current linear and switching power supplies
Voltage monitoring circuits
Current source and sink applications
Zener diode replacements requiring precision references

Voltage Reference Procurement Notes

Verify the specific suffix 'CCM3' against the manufacturer's latest orderable addendum to confirm active status and packaging details. Ensure the design accommodates the commercial operating temperature range of 0°C to 70°C. Confirm that the SOT-23 thermal resistance metrics align with the system's heat dissipation requirements under maximum load conditions.

Voltage Reference Selection Notes

Select this component when space-constrained designs require a precision shunt regulator in a small surface-mount footprint. The LM431CCM3 is appropriate for applications needing programmable output voltages above 2.5 V with tight tolerance requirements. Consider the commercial temperature grade if industrial or automotive ranges are not required.

Voltage Reference Part Context

The LM431 series serves as a widely adopted standard for adjustable shunt regulation, often replacing discrete Zener diodes in precision circuits. The LM431CCM3 variant specifically utilizes the SOT-23 package to minimize board area while maintaining the electrical characteristics of the broader LM431 family. It is part of Texas Instruments' portfolio of power management integrated circuits designed for cost-effective and reliable voltage referencing.
