LM4040CEM3-2.1+T

Overview

The LM4040CEM3-2.1+T is a precision micropower shunt 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 0.5%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +125°C. It utilizes a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm) and supports a shunt current range from 60μA to 15mA.

Feature Summary

Subminiature 3-pin SC70 package designed for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Stable operation without external stabilizing capacitors across any capacitive load
Low dynamic impedance maintains accuracy over wide operating currents

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, temperature grade, and RoHS compliance status. Confirm that the requested part number matches the exact electrical specifications required for the design. Check for automotive qualification requirements if applicable to the target application environment.

Selection Notes

Select this component when a stable, low-power shunt reference is needed in a compact footprint. Ensure the circuit design accommodates the specified minimum operating current of 60μA and maximum shunt current of 15mA. Verify that the thermal dissipation limits are respected under maximum ambient temperature conditions to prevent exceeding the junction temperature rating.

Part Context

This component belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SOT23 and SC70 packages with different accuracy grades ranging from 0.1% to 1%.
