Voltage Reference datasheet and documents for LM431CCZXA

LM431CCZXA

Voltage Reference Overview

The Fairchild Semiconductor LM431CCZXA is a three-terminal adjustable shunt regulator housed in a TO-92 package. It functions as a programmable voltage reference with an output range settable between approximately 2.5V and 36V using two external resistors. The device features a typical dynamic output impedance of 0.2Ω and supports a sink current capability from 1.0mA to 100mA. It operates within a temperature range of -25°C to +85°C, offering low output noise and fast turn-on response suitable for replacing Zener diodes.

Voltage Reference Feature Summary

Programmable output voltage adjustable via external resistors
Low dynamic output impedance for stable regulation
Temperature compensated operation over rated range
Fast turn-on characteristic

Voltage Reference Applications

Precision voltage references
Adjustable power supplies
Battery chargers
Voltage monitoring circuits

Voltage Reference Procurement Notes

Verify the specific suffix 'CC' against official Fairchild documentation to confirm initial accuracy and temperature coefficient specifications. Ensure the TO-92 SIP3 package matches the target PCB footprint. Confirm RoHS compliance status for the specific manufacturing batch prior to integration.

Voltage Reference Selection Notes

Select this component when a low-cost, high-precision adjustable shunt regulator is required in a through-hole package. It serves as a direct replacement for standard Zener diodes where tighter tolerance and lower dynamic impedance are necessary. Verify that the 100mA maximum sink current meets the circuit's load requirements.

Voltage Reference Part Context

This part belongs to the LM431 family of programmable shunt regulators manufactured by Fairchild Semiconductor (now ON Semiconductor). These devices are widely used in industrial and consumer electronics for voltage regulation and reference applications. The TO-92 packaging facilitates easy prototyping and through-hole assembly.
