LM336BMX-5.0

Overview

The LM336BMX-5.0 is a precision shunt voltage reference from the LM336 series, manufactured by Texas Instruments. It provides a fixed nominal output voltage of 5 V with an initial accuracy of ±1%. The device operates in surface-mount SOIC-8 packages and supports a maximum shunt current of 10 mA. It features a temperature coefficient of 20 ppm/°C and functions within a commercial operating temperature range of 0°C to +70°C. Designed as a two-terminal reference diode, it offers low dynamic impedance for stable regulation.

Feature Summary

• Provides a precise 5 V reference voltage suitable for analog circuitry requiring high stability.
• Utilizes a shunt topology to maintain regulated voltage across varying load conditions.
• Features low temperature drift characteristics to ensure consistent performance over thermal changes.

Applications

• Precision measurement systems requiring stable reference voltages
• Analog-to-digital converter (ADC) reference inputs
• Operational amplifier biasing circuits

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required surface-mount configuration and accuracy class. Cross-reference datasheet revisions to validate electrical parameters before integration into design specifications.

Selection Notes

Select this component when a fixed 5 V reference is needed in a compact surface-mount format. Compare against through-hole alternatives if board space permits lower cost options. Verify that the 10 mA current limit meets the application's power dissipation requirements and that the commercial temperature range aligns with environmental constraints.

Part Context

This device belongs to the LM336 family of two-terminal zener-based voltage references. It serves as a monolithic integrated circuit alternative to discrete zener diodes, offering superior temperature stability and lower dynamic impedance. The series includes various fixed voltage options and adjustable variants to support diverse reference needs.

Replacement Considerations

LM336BDR-5.0 is a documented parameter-equivalent substitute within the same series offering identical electrical specifications in a tape-and-reel SOIC-8 package.
