LM4040DIM3-2.1+T

Overview

The LM4040DIM3-2.1+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 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 precise 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 that the specific ordering suffix matches the required package type (SC70) and temperature grade (-40°C to +85°C). Confirm RoHS compliance status indicated by the plus sign in the part number. Ensure the selected component aligns with the specified 1.0% initial accuracy and 150ppm/°C temperature coefficient requirements for your design.

Selection Notes

Select this component when a compact footprint is prioritized alongside standard industrial temperature performance. The 1.0% accuracy grade offers a cost-effective solution compared to tighter tolerance variants. Verify that the application circuit maintains the shunt current between 60μA and 15mA to ensure stable regulation and prevent damage from excessive power dissipation.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family includes various output voltages and accuracy grades available in both SOT23 and SC70 packages. The 'D' designation indicates the 1.0% accuracy class, while 'IM3' specifies the SOT23 package variant; however, datasheet cross-referencing confirms the SC70 package code X3 corresponds to the IX3 suffix, suggesting potential nomenclature variations or specific distributor mapping for the DIM3 designation.
