LM4041BIM3-1.2+T

Overview

The LM4041BIM3-1.2+T is a precision micropower shunt voltage reference manufactured by Analog Devices (Maxim Integrated). It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.2% and a maximum temperature coefficient of 100ppm/°C. The device operates within a wide current range from 60µA to 12mA and features low dynamic impedance for stable performance across varying loads. It is housed in a compact SOT-23-3 surface-mount package and is guaranteed to function over an industrial temperature range of -40°C to +85°C.

Feature Summary

Ultra-small 3-pin SC70 or SOT-23 surface-mount package design
Laser-trimmed resistors ensure precise initial accuracy
Stable operation with any capacitive load without external stabilizing capacitors
Low output noise and wide operating current range

Applications

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

Procurement Notes

Verify the specific suffix 'M3' corresponds to the SOT-23-3 package variant rather than the SC70-3 package. Confirm that the '+T' designation indicates tape-and-reel packaging and lead-free compliance. Ensure the component grade matches the required 0.2% initial accuracy specification for your circuit design.

Selection Notes

Select this component when space constraints require a subminiature footprint compared to standard packages. Choose this part if the application demands high initial accuracy (0.2%) at a lower cost point than the 0.1% grade. Verify that the 12mA maximum shunt current capability aligns with the power dissipation limits of the target PCB layout.

Part Context

This component belongs to the LM4041 family of improved precision micropower shunt voltage references. It shares core bandgap architecture with other grades like LM4041AIM3 and LM4041CIM3 but offers distinct accuracy and thermal specifications. The device utilizes BiCMOS processing and contains 60 transistors to achieve its stable reference characteristics.
