LM4041CIM3-1.2+T

Overview

The LM4041CIM3-1.2+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.5% 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 subminiature SOT23-3 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 SOT23 surface-mount package designed for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy without requiring external stabilizing capacitors
Capable of tolerating any capacitive load while maintaining stability
Bandgap reference technology with curvature correction for stable voltage accuracy

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type (SC70-3 vs. SOT23-3) and temperature grade. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the selected part number matches the required initial accuracy tolerance for your circuit design specifications.

Selection Notes

Select this component when a compact footprint is required alongside high precision. The LM4041CIM3-1.2+T offers a balance of low power consumption and stable output suitable for portable devices. Consider the 0.5% initial accuracy and 100ppm/°C temperature coefficient to ensure they align with the system's overall error budget and thermal operating conditions.

Part Context

This component belongs to the LM4041 series of improved precision micropower shunt voltage references. The series includes various grades offering different levels of initial accuracy, ranging from 0.1% to 1.0%. The LM4041 family is designed to replace larger discrete Zener diodes or bulkier reference ICs in modern electronic designs where size and power efficiency are paramount.
