LM4040BEM3-5.0+T

Overview

The LM4040BEM3-5.0+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 5.000V 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 and supports a shunt current capability ranging from 60μA to 15mA.

Feature Summary

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

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 package type, temperature grade, and RoHS compliance status. Ensure that the selected component matches the required electrical specifications for the target application environment before procurement.

Selection Notes

Select this component when space-constrained designs require a high-precision shunt reference in a small footprint. Verify that the system supply voltage and series resistor values maintain the shunt current between the minimum operating threshold and the maximum continuous dissipation limits across the full operational temperature range.

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 up to +125°C. The 'M3' code identifies the SOT23-3 package configuration.
