LM4040DIM3-5.0-TR

Overview

The LM4040DIM3-5.0-TR is a precision micropower shunt voltage reference manufactured by Microchip Technology, providing a fixed reverse-breakdown voltage of 5.000V. It operates within an industrial temperature range of -40°C to +85°C and features a maximum initial accuracy of ±1% at 25°C. The device utilizes a bandgap reference topology with curvature correction for low dynamic impedance and stable performance across varying currents. Packaged in a subminiature 3-pin SOT-23 surface-mount format, it supports a maximum operating current of 15 mA and requires no output capacitor for stability.

Feature Summary

Bandgap reference design with temperature drift curvature correction ensures stable reverse-breakdown voltage accuracy over wide operating temperatures and currents.
Capable of tolerating capacitive loads without requiring an external output capacitor, simplifying circuit design.
Subminiature SOT-23 package designed specifically for space-critical applications.

Applications

Battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Energy management

Procurement Notes

Verify the specific suffix DIM3 corresponds to the D-grade (±1%) tolerance and TR indicates tape and reel packaging. Confirm the manufacturer is Microchip Technology, as this part number family was previously produced by other entities. Ensure the component meets RoHS compliance standards required for your assembly process.

Selection Notes

Select this component when a fixed 5.0V reference is needed in a compact SOT-23 footprint. It is suitable for designs requiring ±1% initial accuracy and operation up to +85°C. Consider the minimum operating current of approximately 79 µA for the 5.0V version when sizing series resistors for power-constrained applications.

Part Context

This device belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. The LM4040 variant provides fixed voltages including 2.5V, 4.096V, and 5.0V, while the LM4041 offers adjustable or lower fixed options. The family is characterized by low noise and high stability, making it a standard choice for analog reference circuits.
