LM236H-2.5

Overview

The LM236H-2.5 is a two-terminal shunt voltage reference circuit manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It provides a fixed output voltage of 2.49 V with an initial accuracy of 1% and a typical temperature coefficient of 20 ppm/°C. The device operates within a junction temperature range of -55°C to +125°C and supports a maximum shunt current of 10 mA. It is housed in the TO-3 metal can package (TO-206AB), suitable for through-hole mounting in industrial and military environments.

Feature Summary

Provides a precise 2.49 V reference voltage with high initial accuracy
Operates reliably across extended industrial and military temperature ranges
Utilizes robust TO-3 metal can packaging for durability

Applications

Precision analog-to-digital converter references
Industrial control system voltage standards
Military-grade instrumentation circuits

Procurement Notes

Verify the specific suffix 'H' indicates the military/extended temperature grade variant. Confirm the TO-3 package type matches your PCB or chassis mounting requirements. Ensure the 10 mA maximum shunt current rating aligns with your circuit's biasing needs. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 2.49 V reference is required with high stability over wide temperature variations. The TO-3 package offers superior thermal dissipation compared to plastic packages. Consider the 1% initial accuracy for applications demanding tight tolerance without external trimming. Evaluate the 20 ppm/°C temperature coefficient against your system's drift specifications.

Part Context

The LM236 series belongs to Texas Instruments' family of two-terminal voltage reference diodes. It serves as a cost-effective alternative to Zener diodes, offering better temperature stability and lower dynamic impedance. The 'H' suffix typically denotes the military-grade version with extended operating temperatures and stricter performance parameters compared to commercial variants.
