LM4050AEX3-2.5+T

Voltage Reference Overview

The LM4050AEX3-2.5+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 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 features low dynamic impedance. It is housed in a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and is guaranteed to function over a temperature range of -40°C to +125°C.

Voltage Reference Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and accuracy grade. Confirm RoHS compliance status through manufacturer declarations. Ensure the selected component matches the required electrical specifications for the target application environment.

Voltage Reference Selection Notes

Select this component when a compact footprint is required alongside high precision. The 0.1% accuracy grade suits applications demanding tight voltage tolerance. Verify that the operating current remains within the specified 60µA to 15mA range to maintain stability and performance across the full temperature spectrum.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of micropower shunt voltage references. The series offers multiple fixed reverse breakdown voltages including 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SOT23 and SC70 packages with different accuracy grades.

Voltage Reference Replacement Considerations

LM4050BEX3-2.5+T: Offers 0.2% initial accuracy instead of 0.1%. LM4050CEX3-2.5+T: Offers 0.5% initial accuracy instead of 0.1%. LM4050AEM3-2.5+T: Provides identical specifications but utilizes the SOT23-3 package instead of SC70.
