Overview
The LM4040CEM3-2.5+T is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices / Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.500V with an initial accuracy of 0.5%. The device features a maximum temperature coefficient of 100ppm/°C and operates over an extended industrial temperature range from -40°C to +125°C. It supports a wide operating current range from 60μA to 15mA and utilizes a subminiature 3-pin SOT23 surface-mount package.
Feature Summary
- Laser-trimmed resistors ensure precise initial accuracy across multiple grades
- Stable operation without requiring external stabilizing capacitors
- Capable of tolerating any capacitive load directly at the output
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 that the 'E' designation corresponds to the extended temperature range (-40°C to +125°C) rather than the standard industrial range. Ensure the ordering part number matches the required 0.5% initial accuracy grade for your design specifications.
Selection Notes
Select this component when space constraints require a subminiature 3-pin package compared to larger alternatives. Choose this specific grade if the design requires guaranteed stability over the full -40°C to +125°C temperature range while maintaining low power consumption suitable for battery-operated applications.
Part Context
This device belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers various fixed breakdown voltages including 2.048V, 3.000V, 4.096V, and 5.000V. Different letter codes denote varying initial accuracy grades ranging from 0.1% to 1.0%, allowing designers to balance precision requirements against cost and performance needs.
