LM4040DIM3X-5.0

Overview

The LM4040DIM3X-5.0 is a precision micropower shunt voltage reference manufactured by Texas Instruments, providing a fixed reverse breakdown voltage of 5 V. It operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 150 ppm/°C. The device offers an initial accuracy tolerance of ±1% at 25°C and supports a wide operating current range from 62 µA to 15 mA. Packaged in the compact SOT-23-3L surface-mount format, it eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load.

Feature Summary

• Eliminates the need for external stabilizing capacitors while maintaining stability with any capacitive load
• Utilizes bandgap reference temperature drift curvature correction and low dynamic impedance for stable performance
• Employs fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure specified accuracy

Applications

• Portable, battery-powered equipment
• Data acquisition systems
• Instrumentation
• Process controls
• Precision audio components

Procurement Notes

Verify that the ordering suffix 'X' corresponds to the specific reel packaging configuration required for your assembly line. Confirm the D-grade tolerance specification matches the design requirements for the 5 V output. Ensure the industrial temperature grade meets the operational environmental limits of the target application.

Selection Notes

Select this component when space constraints necessitate the use of the SOT-23 package. Choose this part if the design requires a fixed 5 V reference without the complexity of adding external compensation capacitors. Consider the 150 ppm/°C temperature coefficient as the limiting factor for thermal stability requirements.

Part Context
