LM4040AEM3-5.0+T

Overview

The LM4040AEM3-5.0+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 0.1%. 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 wide operating current range from 60µA to 15mA.

Feature Summary

Ultra-small 3-pin SOT23 surface-mount package
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 suffix characters in the part number against official manufacturer documentation to confirm exact electrical grades, temperature ranges, and packaging configurations. Ordering information tables define distinct performance characteristics for different suffixes; do not assume functional interchangeability based solely on the base model name.

Selection Notes

Select this component when high precision and low power consumption are required in space-constrained designs. The 0.1% accuracy grade ensures tight tolerance at room temperature, while the extended temperature rating supports demanding industrial environments. Ensure the design maintains the minimum operating current to guarantee stable regulation.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages and varying accuracy grades. The 'E' designation indicates the extended temperature version (-40°C to +125°C), distinguishing it from the industrial grade (-40°C to +85°C) variants.
