LM4040CIM3-2.5+T

Overview

The LM4040CIM3-2.5+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 ±0.5%. The device features a temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +85°C. It utilizes a subminiature 3-pin SOT-23 surface-mount package. The component supports a shunt current range from 60μA to 15mA, ensuring stable performance across varying operating conditions.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy for the bandgap voltage reference.
Operates stably without requiring external stabilizing capacitors while tolerating any capacitive load.
Low dynamic impedance maintains accurate reverse breakdown voltage over wide current ranges.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the selected variant matches the required initial accuracy and temperature coefficient specifications for the target application environment.

Selection Notes

Select this component when space-critical designs require a precision shunt reference in a small footprint. The 0.5% accuracy grade offers a balance between cost and performance. Verify that the circuit design accommodates the minimum operating current of 60μA and does not exceed the maximum shunt current limits during operation.

Part Context

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

FAQ

Does the LM4040CIM3-2.5+T require an external capacitor for stability?

No, the device does not require an external stabilizing capacitor and is guaranteed to be stable with any capacitive load.

What is the pin configuration for the 3-pin package?

Pin 1 is the positive terminal, Pin 2 is the negative terminal, and Pin 3 is no connection (N.C.). Pin 3 must be left unconnected or connected to Pin 2.
