LM4040BIM3-2.1+T

Overview

The LM4040BIM3-2.1+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 2.048V 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. Packaged in a subminiature 3-pin SOT-23 surface-mount format, it supports a wide operating current range from 60µA to 15mA.

Feature Summary

Laser-trimmed resistors ensure precise initial accuracy for stable performance.
Operates without external stabilizing capacitors while tolerating any capacitive load.
Utilizes bandgap principle to maintain constant output voltage across wide current ranges.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature grade, and RoHS compliance status. Ensure the selected variant matches the required initial accuracy and operating temperature range for the target application environment before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require a high-precision shunt reference. The SOT-23 package offers significant size reduction compared to standard packages. Verify that the circuit design maintains the minimum operating current of 60µA and limits the maximum shunt current to 15mA to ensure proper regulation and stability.

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, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in both SOT-23 and SC70 packages with different accuracy grades ranging from 0.1% to 1%.

FAQ

Does the LM4040BIM3-2.1+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.
