LM336M-5.0

Overview

The LM336M-5.0 is a precision shunt voltage reference from the LM336 series, manufactured by Texas Instruments. It provides a nominal reference voltage of 5.0 V with an initial accuracy of ±1%. The device operates in a surface-mount SOIC-8 package and supports a maximum shunt current of 10 mA. It features a temperature coefficient of 20 ppm/°C and maintains operation within a commercial temperature range of 0°C to 70°C. The component exhibits a dynamic impedance of 0.6 Ω and offers low load regulation characteristics suitable for stable voltage referencing applications.

Feature Summary

• Provides a fixed 5.0 V precision reference voltage with high initial accuracy
• Utilizes shunt topology for flexible positive or negative voltage referencing
• Features low dynamic impedance for stable performance under varying load conditions

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital voltmeter calibration circuits
• Operational amplifier biasing networks

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and tolerance grades. Ensure the selected variant matches the required operating temperature range and packaging type for your printed circuit board design. Cross-reference the datasheet revision history to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 5.0 V reference is required in a surface-mount configuration. The ±1% initial accuracy makes it suitable for general-purpose precision applications where tight tolerance is necessary but not critical. Consider the 10 mA maximum shunt current limit when designing the series resistor network to ensure proper regulation across the expected load variations.

Part Context

The LM336M-5.0 belongs to the LM336 family of two-terminal zener diode references. This series is designed to replace standard zener diodes by offering significantly lower dynamic impedance and better temperature stability. The 'M' suffix indicates the SOIC-8 surface-mount package, distinguishing it from through-hole variants like the LM336Z.

Replacement Considerations

Direct replacements include other LM336M-5.0 units from Texas Instruments or equivalent 5.0 V shunt references in SOIC-8 packages from other manufacturers, provided pinouts and electrical specifications match.
