LM4050AEM3-2.5/V+T

Voltage Reference Overview

The LM4050AEM3-2.5/V+T is a precision two-terminal shunt-mode bandgap voltage reference manufactured by Analog Devices/Maxim Integrated. It provides a fixed reverse breakdown voltage of 2.500V 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 SOT-23 surface-mount package. It is qualified under the AEC-Q100 standard for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• AEC-Q100 qualified for automotive reliability
• Laser-trimmed resistors ensure high initial accuracy
• Capable of tolerating capacitive loads without external stabilizing capacitors

Voltage Reference Applications

• Automotive electronics systems
• Portable battery-powered equipment
• Industrial process controls

Voltage Reference Procurement Notes

Verify that the specific /V suffix confirms AEC-Q100 qualification status as documented in the official ordering information table. Confirm the physical package type matches the required SOT-23 footprint for the design. Ensure the component grade meets the necessary initial accuracy specifications for the target application environment.

Voltage Reference Selection Notes

Select this component when automotive-grade reliability is required alongside precise voltage referencing. The SOT-23 package offers a larger footprint than SC70 alternatives, which may simplify layout constraints. Verify that the operating current requirements fall within the specified 60µA to 15mA range to maintain stability and accuracy.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of micropower shunt voltage references. The 'A' designation indicates the highest accuracy grade (0.1%), while the '/V' suffix specifically denotes AEC-Q100 automotive qualification. The 'EM3' code identifies the SOT-23 package variant, distinguishing it from the smaller SC70 options available in the series.
