LM336BMX-5.0

Overview

The LM336BMX-5.0 is a shunt voltage reference IC manufactured by National Semiconductor, now part of Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of ±2%. The device supports a maximum shunt current of 10 mA and operates within a temperature range of 0°C to +70°C. It is housed in an 8-SOIC narrow surface-mount package.

Feature Summary

• Provides a stable fixed 5V reference output suitable for precision applications
• Operates as a shunt regulator with defined current limits
• Designed for surface-mount integration via SOIC-8 packaging

Applications

• Precision voltage regulation circuits
• Analog-to-digital converter reference sources
• Temperature compensated power supplies

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix (e.g., NOPB) if exact compliance or legacy sourcing is required. Ensure the package type matches the design footprint. Cross-reference datasheets between NS and TI to confirm pinout consistency.

Selection Notes

Select this component when a fixed 5V shunt reference is required in a surface-mount form factor. Consider the ±2% accuracy and 10 mA current limit against circuit demands. Verify thermal operating ranges meet environmental specifications. Compare against other LM336 variants for different voltage outputs or package styles.

Part Context

This part belongs to the LM336 family of adjustable and fixed shunt voltage references. The 'BMX' suffix indicates the specific surface-mount package and tape-and-reel packaging configuration. The '5.0' denotes the fixed 5-volt output version. This series is widely used for providing stable reference voltages in analog signal processing.

Replacement Considerations

LM336BMX-5.0/NOPB is a direct equivalent from Texas Instruments following the acquisition. LM336Z-5.0 is a through-hole alternative with similar electrical characteristics but different packaging.
