LM4040BIM3-3.0/NOPB

Overview

The LM4040BIM3-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3 V. It features an initial accuracy of 0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a SOT-23-3 surface-mount package with a maximum shunt current of 15 mA and a temperature coefficient of 150 ppm/°C.

Feature Summary

Provides stable precision voltage reference in compact SOT-23-3 package
Micropower operation suitable for battery-powered applications
High initial accuracy ensures reliable circuit performance

Applications

Portable instrumentation requiring precise voltage references
Battery-operated measurement systems
Data acquisition systems needing stable reference voltages

Procurement Notes

Verify the exact part number including the suffix /NOPB to ensure lead-free compliance. Confirm the specific voltage rating matches the design requirement of 3.0 V. Check the manufacturer's latest documentation for any pinout or handling updates before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 3 V reference is required in a small footprint. Consider the 15 mA maximum current limit for load requirements. Evaluate the 150 ppm/°C temperature coefficient against environmental conditions. Ensure the SOT-23-3 package fits the PCB layout constraints.

Part Context

This component belongs to the LM4040 series of micropower shunt voltage references. It offers a fixed voltage option in a three-terminal configuration. The series is designed for applications requiring high accuracy and low power consumption in space-constrained environments.
