LM4040BEM3-3.0+T

Overview

The LM4040BEM3-3.0+T is a precision, two-terminal shunt mode bandgap 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 0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +125°C. It utilizes a 3-pin SOT23 surface-mount package.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy across multiple grades.
Low dynamic impedance maintains stable reverse breakdown voltage over wide operating currents.
Stable operation guaranteed without external stabilizing capacitors under any capacitive load.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical tolerances, temperature ranges, and package variations. Confirm RoHS compliance status directly from the datasheet or authorized distributor listings before procurement.

Selection Notes

Select this component for applications requiring high precision in space-constrained designs. Ensure the design accommodates the specified shunt current limits and thermal dissipation requirements for the industrial temperature grade.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'B' designation indicates a 0.2% initial accuracy grade, while the 'E' suffix specifies the extended industrial temperature range capability up to +125°C.
