LM4050AEM3-5.0/V+T

Voltage Reference Overview

The LM4050AEM3-5.0/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 voltage of 5.000V with an initial accuracy of 0.1% and a maximum temperature coefficient of 50ppm/°C. The device operates within a wide current range from 60µA to 15mA and is housed in a 3-pin SOT23 surface-mount package. Specifications are guaranteed over an operating temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Laser-trimmed resistors ensure high initial accuracy across multiple grades.
• Capable of maintaining stable reverse breakdown voltage over a wide operating current range.
• Does not require external stabilizing capacitors for frequency stability.
• Ensures stability when connected to any capacitive loads.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific /V suffix indicates AEC-Q100 automotive qualification status as defined in the official ordering information. Confirm that the SOT23 package code matches the required footprint for the target PCB design. Ensure the selected grade meets the strictest tolerance requirements for the intended circuit environment.

Voltage Reference Selection Notes

Select this component when space constraints favor the SOT23 package over the smaller SC70 variant while requiring automotive-grade reliability. The 0.1% accuracy grade is suitable for high-precision analog-to-digital converter references. Verify that the source resistor limits the shunt current below the 15mA maximum limit under all supply voltage conditions.
