LM4040BIM3-10.0

Overview

The LM4040BIM3-10.0 is a precision micropower shunt voltage reference from Texas Instruments, providing a fixed reverse breakdown voltage of 10 V. It operates within an industrial temperature range of -40°C to +85°C and features a maximum initial tolerance of ±0.2% at 25°C. The device supports a wide operating current range from 100 μA to 15 mA with a maximum temperature coefficient of 150 ppm/°C. Packaged in a compact SOT-23 format, it eliminates the need for external stabilizing capacitors while tolerating capacitive loads.

Feature Summary

• Eliminates the need for external stabilizing capacitors
• Tolerates capacitive loads without stability issues
• Utilizes fuse and Zener-zap reverse breakdown voltage trim for accuracy

Applications

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

Procurement Notes

Verify the specific grade suffix 'B' corresponds to the required ±0.2% tolerance and confirm the '-10.0' designation matches the 10 V output requirement. Ensure the SOT-23 package variant aligns with PCB layout constraints. Cross-reference the datasheet revision date to confirm compliance with current manufacturing standards and environmental directives.

Selection Notes

Select this component when space-critical applications require a stable 10 V reference in a sub-miniature surface-mount package. It is suitable for designs needing high accuracy without external compensation components. Consider the minimum operating current of 100 μA for the 10 V version when designing biasing circuits compared to lower voltage variants.
