LM4040DIM3-10.0

Overview

The LM4040DIM3-10.0 is a precision micropower shunt voltage reference manufactured by Texas Instruments, housed in a SOT-23 package. It provides a fixed reverse breakdown voltage of 10 V with an initial accuracy tolerance of ±1% at 25°C. The device operates within an industrial temperature range from -40°C to +85°C and features a maximum temperature coefficient of 150 ppm/°C. It supports a wide operating current range from 100 μA to 15 mA.

Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Utilizes bandgap reference temperature drift curvature correction for stable performance across temperatures
• 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 the specific suffix 'D' indicates the D-grade tolerance level and confirm the '-10.0' designation corresponds to the 10 V output variant. Ensure the ordering part number matches the required package type and temperature grade specifications before procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for space-critical applications. It is suitable for designs needing a fixed 10 V reference without external compensation capacitors. Consider the 150 ppm/°C temperature coefficient and ±1% initial accuracy against system requirements.
