LM4040AEM3-5.0/V+

Overview

The LM4040AEM3-5.0/V+ 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% 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 is housed in a subminiature 3-pin SOT23 surface-mount package.

Feature Summary

Ultra-small 3-pin SOT23 package designed for space-critical applications
High precision with 0.1% maximum initial accuracy at 25°C
Stable operation without external stabilizing capacitors across any capacitive load
Automotive-grade qualification compliant with AEC-Q100 standards

Applications

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

Procurement Notes

Verify that the specific part number includes the /V suffix to confirm AEC-Q100 automotive qualification status. Confirm the package type matches the required SOT23 footprint. Ensure the operating environment remains within the specified -40°C to +125°C range to maintain the guaranteed 0.1% accuracy and thermal performance specifications.

Selection Notes

Select this component when high precision and automotive reliability are required in a compact form factor. The 0.1% accuracy grade ensures tight tolerance control. Verify that the circuit design accommodates the minimum operating current of 60μA and does not exceed the maximum shunt current of 15mA to ensure stable regulation and prevent damage.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in different accuracy grades (0.1%, 0.2%, 0.5%, 1%) and packages (SC70, SOT23) to suit various design constraints.
