LM185WG-1.2/883

Overview

The LM185WG-1.2/883 is a micropower voltage reference diode manufactured by Texas Instruments, designed for high-reliability applications requiring strict environmental compliance. This component provides a stable 1.2V output and is qualified to the MIL-STD-883 standard, ensuring suitability for military and aerospace environments. It features low power consumption characteristics typical of the LM185 series, making it efficient for battery-operated or power-sensitive systems. The device utilizes a TO-92 package configuration, offering robust mechanical integrity and thermal performance under rigorous operational conditions defined by the /883 suffix.

Feature Summary

• Qualified to MIL-STD-883 standards for military and aerospace reliability requirements
• Provides a precise 1.2V micropower voltage reference output
• Utilizes a rugged TO-92 package suitable for harsh environments

Applications

• Military electronic systems requiring radiation-hardened or high-reliability references
• Aerospace instrumentation and control circuits
• Precision measurement equipment operating in extreme temperature ranges

Procurement Notes

Verify that the ordering part number explicitly includes the /883 suffix to ensure qualification to MIL-STD-883 standards. Confirm the specific revision level and lot traceability requirements with the manufacturer or authorized distributor prior to purchase. Ensure compatibility with existing board layouts for the TO-92 package form factor.

Selection Notes

Select this component when application requirements mandate compliance with military quality standards such as MIL-STD-883. It is appropriate for designs needing a stable 1.2V reference with low quiescent current in a through-hole TO-92 package. Consider radiation tolerance data if the environment involves ionizing radiation exposure.

Part Context

This device belongs to the LM185 family of micropower voltage reference diodes from Texas Instruments.
