LM4040CIM3X-4.1

Overview

The LM4040CIM3X-4.1 is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed reverse breakdown voltage of 4.096 V. It operates within an industrial temperature range of -40°C to +85°C and utilizes a SOT-23 surface-mount package. The device provides a C-grade initial tolerance of ±0.5% at 25°C with a maximum temperature coefficient of 100 ppm/°C. Designed for space-critical applications, 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 Zener-zap reverse breakdown voltage trim for accuracy

Applications

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

Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm that the 'CIM3' designation corresponds to the C-grade tolerance and industrial temperature range requirements. Ensure the 4.1V output matches the system reference needs. Check for RoHS compliance status in the latest datasheet revision before final procurement.

Selection Notes

Select this component for designs requiring a compact SOT-23 footprint with stable shunt regulation. The C-grade offers a balance between cost and precision for general instrumentation. Verify that the minimum operating current of 68 μA fits the power budget constraints. Consider thermal derating if ambient temperatures approach the upper limit of the industrial range.

Part Context

This part belongs to the LM4040-N family of precision micropower shunt voltage references. The family includes various voltage options and grades (A through E) to suit different accuracy and temperature requirements. The LM4040-N series is designed for applications where small size and low power consumption are critical design factors.
