LM4040BIM3-2.5+T

Overview

The LM4040BIM3-2.5+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.500V with an initial accuracy of 0.2%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +85°C. It utilizes a SOT-23-3 surface-mount package and supports a shunt current range from 60μA to 15mA.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy for stable performance.
Capable of maintaining stability with any capacitive load without requiring external stabilizing capacitors.
Operates over a wide operating current range suitable for power-restricted designs.

Applications

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

Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging when sourcing. Confirm the 'I' designation in the base model corresponds to the industrial temperature range (-40°C to +85°C) rather than extended ranges. Ensure compatibility with the SOT-23-3 footprint during PCB layout review.

Selection Notes

Select this component when a 2.5V reference with 0.2% tolerance is required in a compact SOT-23-3 form factor. Consider the 100ppm/°C temperature coefficient for thermal drift requirements. Verify that the application's minimum current draw remains above 60μA to maintain regulation.

Part Context

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