LM4040AEM3-3.0+T

Overview

The LM4040AEM3-3.0+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse-breakdown output voltage of 3.000V with an initial accuracy of 0.1%. The device features a maximum temperature coefficient of 100ppm/°C and operates within a temperature range of -40°C to +125°C. It utilizes a 3-pin SOT23 surface-mount package and supports a shunt current range from 60μA to 15mA.

Feature Summary

Ultra-small 3-pin SC70 or SOT23 surface-mount package design
Laser-trimmed resistors ensure precise initial accuracy
Stable operation without external stabilizing capacitors
Capable of tolerating any capacitive load

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact electrical characteristics, package type, and temperature range. Confirm RoHS compliance status and lead-free packaging requirements before procurement. Ensure the selected variant matches the required operating temperature and accuracy specifications for the target application.

Selection Notes

Select this component when high precision and low power consumption are critical in space-constrained designs. The A-grade accuracy ensures tight tolerance at room temperature. Verify that the circuit design maintains the minimum operating current above 60μA while ensuring the maximum shunt current does not exceed 15mA during all operating conditions.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. The family offers multiple fixed reverse-breakdown voltages including 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Variants are available in different accuracy grades (A, B, C, D) and temperature ranges (I for industrial, E for extended).

FAQ

Does the LM4040 require an external capacitor for stability?

No, the LM4040 does not require an external stabilizing capacitor and remains stable with any capacitive load.

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

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.
