LM4040CEX3-3.3+T

Overview

The LM4040CEX3-3.3+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 3.3V 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 15mA and is guaranteed over the extended industrial temperature range of -40°C to +125°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 the specific ordering suffix against official manufacturer documentation to confirm exact electrical parameters, temperature range, and package type. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels before procurement.

Selection Notes

Select this component when a compact footprint is required alongside stable voltage referencing in power-constrained designs. Ensure the application circuit maintains the minimum operating current of 60μA while keeping the shunt current below the 15mA maximum limit to maintain regulation stability.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages including 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V across various accuracy grades and packages like SOT23-3 and SC70-3.
