LM236H-5.0

Overview

The LM236H-5.0 is a precision shunt voltage reference circuit manufactured by Texas Instruments, providing a fixed output voltage of 5.0 V. It operates within an extended temperature range of -55°C to +125°C and utilizes a TO-3 metal can package for robust through-hole mounting. The device features a maximum initial accuracy of 1% and a typical temperature coefficient of 20 ppm/°C. It supports a maximum shunt current of 10 mA with a minimum operating current of 600 µA, ensuring stable regulation across industrial applications.

Feature Summary

• Provides a stable fixed 5.0 V reference output suitable for precision analog circuits
• Operates reliably across an extended industrial temperature range from -55°C to +125°C
• Delivers high initial accuracy with a maximum tolerance of 1%
• Utilizes a durable TO-3 metal can package for secure through-hole integration

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Industrial control system voltage regulation
• High-accuracy measurement instrumentation
• Temperature-compensated oscillator circuits

Procurement Notes

Verify the specific suffix 'H' indicates the extended temperature range (-55°C to +125°C) and TO-3 package configuration. Confirm that the '5.0' designation corresponds to the fixed 5.0 V output voltage rather than other variants in the LM236 family. Ensure compatibility with through-hole assembly processes given the metal can form factor.

Selection Notes

Select this component when a fixed 5.0 V reference with high accuracy is required for harsh environments. The TO-3 package offers superior thermal dissipation compared to plastic packages. Consider the 10 mA current limit for load requirements and verify that the 600 µA minimum operating current fits the biasing constraints of the target circuit design.

Part Context

The LM236 series comprises integrated zener reference diodes designed for precision voltage regulation. The LM236H-5.0 represents the high-temperature variant within this family, distinguished by its military-grade temperature rating and hermetic metal packaging. It serves as a fundamental building block for power management and signal conditioning systems requiring stable reference potentials.

Replacement Considerations

Direct substitutes include the LM136H-5.0/NOPB for equivalent performance specifications. Verify pinout compatibility and thermal characteristics when transitioning between manufacturers or package variations within the shunt reference category.
