LM4040AIX3-5.0+T

Overview

The LM4040AIX3-5.0+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 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 +85°C. It utilizes a subminiature 3-pin SC70 surface-mount package.

Feature Summary

• Ultra-small 3-pin SC70 package designed for space-critical applications
• Laser-trimmed resistors ensure high precision with 0.1% initial accuracy
• Stable operation without external stabilizing capacitors across any capacitive load

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical tolerances, temperature ranges, and package variations. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels before procurement.

Selection Notes

Select this component when precise voltage referencing is required in compact designs. Ensure the operating current remains between 60μA and 15mA for optimal performance. Verify that the ambient temperature does not exceed the specified limits for the selected grade.

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 'IX3' specifies the SC70 package and industrial temperature range. The '+T' suffix denotes tape and reel packaging.

Replacement Considerations

LM4040AIM3-5.0+T offers identical electrical specifications but uses the SOT23-3 package instead of SC70.
