LM4040CIM3-2.1+T

Overview

The LM4040CIM3-2.1+T is a precision micropower shunt voltage reference manufactured by Analog Devices / Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.048V with an initial accuracy of 0.5% and a temperature coefficient of 100ppm/°C. The device operates within a temperature range of -40°C to +85°C and supports a shunt current range from 60μA to 15mA. It is housed in a subminiature 3-pin SC70 surface-mount package.

Feature Summary

Ultra-small 3-pin SC70 package for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Stable operation without external stabilizing capacitors
Capable of tolerating any capacitive load

Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process controls
Automotive systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, accuracy grade, and temperature range. Ensure compatibility with RoHS compliance requirements if applicable. Confirm that the SC70 footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a compact form factor is required alongside stable voltage referencing. The 0.5% accuracy and 100ppm/°C temperature coefficient suit general-purpose precision applications. Consider the wide operating current range for designs requiring low quiescent power consumption or higher drive capability.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. The series offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SOT23 and SC70 packages with different accuracy grades ranging from 0.1% to 1%.
