LM4040CIM3-10.0

Overview

The LM4040CIM3-10.0 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 accuracy of ±0.5% at 25°C. The device requires a minimum operating current of 100 μA and supports a maximum operating current of 15 mA. It utilizes a SOT-23 surface-mount package with three pins.

Feature Summary

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

Applications

Data acquisition systems
Instrumentation
Process controls
Precision audio components

Procurement Notes

Verify the specific suffix 'CIM3' corresponds to the C-grade tolerance (±0.5%) and industrial temperature range (-40°C to +85°C). Confirm the 'M3' designation indicates the SOT-23 package type. Ensure the '-10.0' suffix matches the required 10 V output voltage. Check for RoHS compliance status in the latest manufacturer documentation.

Selection Notes

Select this component when a fixed 10 V reference is needed in space-constrained designs using SOT-23 packages. It is suitable for applications requiring low power consumption with a minimum operating current of 100 μA. Consider the ±0.5% initial accuracy and 100 ppm/°C temperature coefficient for precision requirements.

Part Context

This part belongs to the LM4040-N family of precision micropower shunt voltage references. The family offers various fixed voltages including 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. The LM4040 series is designed for sub-miniature packages like SC70 and SOT-23, making it ideal for portable and battery-powered equipment.
