LM4040DIX3-2.5+T

Overview

The LM4040DIX3-2.5+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 2.500V with an initial accuracy of 1.0%. The device operates within a temperature range of -40°C to +85°C and features a maximum average reverse voltage temperature coefficient of 150ppm/°C at 1mA current. It supports a wide operating current range from 60μA to 15mA.

Feature Summary

Ultra-small 3-pin SC70 surface-mount package for space-critical designs
Laser-trimmed resistors ensure precise initial accuracy
Stable operation without external stabilizing capacitors across any capacitive load

Applications

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

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging configuration. Confirm the 'D' grade designation corresponds to the required 1.0% initial accuracy and 150ppm/°C temperature coefficient specifications. Ensure the component meets lead-free/RoHS compliance requirements as indicated by the '+' symbol in the ordering information.

Selection Notes

Select this component when a compact footprint is prioritized over higher precision grades. The D-grade offers lower cost but wider tolerance compared to A or B grades. Verify that the application's minimum operating current exceeds 60μA and maximum shunt current remains below 15mA to maintain regulation stability.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It utilizes a bandgap principle to produce stable voltage. The SC70 package is approximately 50% smaller than comparable SOT23 packages. The device behaves similarly to an ideal Zener diode while maintaining low dynamic impedance.
