LM4040CEM3-5.0/V+T

Overview

The LM4040CEM3-5.0/V+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 0.5% and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60μA to 15mA and is guaranteed over the industrial temperature range of -40°C to +125°C. It utilizes a subminiature 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 accuracy over varying operating temperatures and currents.
No external stabilizing capacitor is required while ensuring stability with any capacitive load.

Applications

Portable, Battery-Powered Equipment
Notebook Computers
Cell Phones
Industrial Process Controls
Automotive

Procurement Notes

Verify that the /V suffix confirms AEC-Q100 automotive qualification status as specified in the manufacturer's ordering information table. Confirm the specific package code matches the required SOT23 footprint for your design. Ensure the component grade aligns with the necessary initial accuracy and temperature coefficient specifications for your application environment.

Selection Notes

Select this part when space constraints require a subminiature 3-pin package compared to larger alternatives. Choose this specific 5.000V version if a higher reference voltage is needed compared to standard 2.5V or 3.3V options. Consider the 0.5% initial accuracy and 100ppm/°C temperature coefficient limits to ensure they meet the system's precision requirements under varying thermal conditions.

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, 3.000V, 3.3V, and 4.096V. Different suffixes indicate variations in accuracy grades, temperature ranges, and packaging types such as SC70 or SOT23.
