LM4040CIM3-3.0+T

Overview

The LM4040CIM3-3.0+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 3.000V with an initial accuracy of 0.5%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +85°C. It utilizes a subminiature 3-pin SOT-23 surface-mount package, supports a shunt current range from 60μA to 15mA, and maintains stability without requiring external capacitors.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy across multiple grades.
Operates stably with any capacitive load without requiring external stabilizing capacitors.
Low dynamic impedance ensures stable reverse breakdown voltage accuracy over wide operating currents.

Applications

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

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging when sourcing. Confirm that the 'I' designation corresponds to the industrial temperature range (-40°C to +85°C) rather than the extended range. Ensure the ordering part number matches the required 0.5% accuracy grade (C) for your design specifications.

Selection Notes

Select this component when space constraints require a subminiature 3-pin SOT-23 package. Choose this model if the application demands a fixed 3.000V reference with 0.5% initial accuracy. Verify that the operating environment remains within the specified -40°C to +85°C range, as higher temperature variants exist for extended ranges.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers various fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.3V, 4.096V, and 5.000V. Different letter codes denote varying accuracy grades and temperature ranges within the same product line.
