LM4040BIM3X-5.0

Overview

The LM4040BIM3X-5.0/NOPB is a fixed shunt voltage reference from the LM4040-N series, manufactured by Texas Instruments. It provides a nominal output voltage of 5 V with an initial accuracy of ±0.2%. The device operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. Designed for surface-mount applications, it utilizes a compact SOT-23 package.

Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high accuracy
• Bandgap reference temperature drift curvature correction ensures stable performance over wide operating temperatures

Applications

• Portable, battery-powered equipment
• Data acquisition systems
• Instrumentation
• Process controls
• Automotive electronics

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and confirms the exact manufacturer designation as Texas Instruments. Ensure the ordering code matches the required tolerance grade and package type. Confirm availability status directly with authorized distributors or the manufacturer, as production data may change.

Selection Notes

Select this component when space-critical designs require a precision shunt reference in a sub-miniature SOT-23 package. It is suitable for applications needing fixed 5 V references without external stabilization components. Consider the ±0.2% initial accuracy and 100 ppm/°C temperature coefficient against system requirements.

Part Context

This part belongs to the LM4040-N family of micropower shunt voltage references. The family offers various fixed reverse breakdown voltages including 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. The LM4040-N series is designed for easy integration into space-constrained circuits due to its small footprint and capacitor-less operation.
