LM4040DEX3-2.1+T

Overview

The LM4040DEX3-2.1+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 2.048V with an initial accuracy of 1.0% and a maximum temperature coefficient of 150ppm/°C. The device operates within a wide current range from 60μA to 15mA and supports an industrial temperature range of -40°C to +125°C. It is housed in a subminiature 3-pin SC70 surface-mount package.

Feature Summary

Ultra-small 3-pin SC70 package designed for space-critical applications
Stable operation without requiring external stabilizing capacitors
Capable of tolerating any capacitive load directly at the output

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor channels before final procurement decisions are made.

Selection Notes

Select this component when a compact footprint is necessary alongside stable shunt reference performance. Ensure the design accommodates the specified 15mA maximum shunt current and verify that the operating environment remains within the guaranteed -40°C to +125°C temperature limits.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The series offers multiple fixed voltage options and varying accuracy grades. The 'D' designation indicates the 1.0% accuracy tier, while 'EX3' specifies the extended temperature range and SC70 package configuration.
