LM103H-3.3/883

Overview

The LM103H-3.3/883 is a precision micropower voltage reference integrated circuit manufactured by Texas Instruments and distributed by Rochester Electronics under the MIL-PRF-38534 qualified /883 suffix. This device provides a stable 3.3V output with low temperature coefficient characteristics, designed for high-reliability applications requiring strict environmental compliance. It utilizes a monolithic silicon planar Zener diode structure to achieve precise regulation without external components.

Feature Summary

MIL-PRF-38534 qualified for high-reliability environments
Precision micropower voltage reference operation
Low temperature coefficient for stability
Monolithic silicon planar construction

Applications

Military aerospace instrumentation
High-reliability data acquisition systems
Precision analog-to-digital converter references
Harsh environment sensor conditioning

Procurement Notes

Verify the specific revision level and lot traceability documentation upon order confirmation. Ensure that the /883 suffix matches the required MIL-PRF-38534 qualification standards for your project. Confirm package integrity and lead condition prior to assembly to maintain reliability specifications.

Selection Notes

Select this component when military-grade reliability and long-term availability are critical. It serves as a drop-in replacement for standard commercial voltage references in space-constrained, high-stress designs. Evaluate thermal management requirements based on the specified power dissipation limits in the official datasheet.

Part Context

Rochester Electronics specializes in the lifecycle management of obsolete and hard-to-find semiconductors. The LM103 series represents a legacy line of precision references originally produced by Texas Instruments. Distribution through Rochester ensures continued supply for defense and industrial sectors requiring proven technology.

Replacement Considerations

Consult the official Texas Instruments LM103 datasheet for pin-compatible alternatives. Verify electrical parameter equivalence before substituting with other manufacturers' voltage references.
