LM4040AEX3-2.5+T

Overview

The LM4040AEX3-2.5+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.500V 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 extended industrial temperature range of -40°C to +125°C. It utilizes a subminiature 3-pin SC70 surface-mount package.

Feature Summary

Ultra-small 3-pin SC70 package designed for space-critical applications
High precision with 0.1% maximum initial accuracy
Stable operation without requiring external stabilizing capacitors
Capable of tolerating any capacitive load

Applications

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

Procurement Notes

Verify the specific ordering suffixes against official manufacturer documentation to confirm exact specifications such as temperature range and packaging format. Confirm RoHS compliance status through the datasheet or component markings. Ensure that the selected variant matches the required operating conditions and accuracy grades before procurement.

Selection Notes

Select this component when high precision and low power consumption are critical in compact designs. The 0.1% accuracy grade ensures tight voltage tolerance at room temperature. Verify that the application environment stays within the specified -40°C to +125°C operational limits to maintain performance guarantees.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'A' designation indicates the highest accuracy grade (0.1%), while 'EX3' specifies the SC70 package and extended temperature range. The '+T' suffix denotes tape and reel packaging suitable for automated assembly processes.

Replacement Considerations

LM4040BEX3-2.5+T offers 0.2% accuracy. LM4040CEX3-2.5+T provides 0.5% accuracy. LM4040DEX3-2.5+T features 1.0% accuracy. All variants share identical pinouts and package dimensions.
