LM4040CEM3X-5.0/NOPB

Overview

The LM4040CEM3X-5.0/NOPB is a fixed shunt precision voltage reference from Texas Instruments, providing a nominal output of 5 V. It operates within a temperature range of -40°C to +85°C and features an initial accuracy of ±0.5%. The device exhibits a temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 15 mA. Packaged in a compact SOT-23 form factor with dimensions of 2.92 mm by 0.93 mm, it utilizes surface-mount technology for efficient integration into space-constrained electronic designs.

Feature Summary

Provides stable fixed voltage reference via shunt topology
Operates reliably across extended industrial temperature ranges
Designed for low-power applications with micropower consumption

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring precise analog references
Microcontroller power supply monitoring circuits

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times through authorized distributors. Validate that the selected package variant matches the intended PCB footprint and thermal management strategy before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V reference with moderate precision is required in a small surface-mount package. Consider the 150 ppm/°C temperature coefficient for thermal stability needs. Ensure the circuit design accommodates the minimum operating current specifications inherent to shunt reference topologies for optimal performance.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various accuracy grades and output voltages within the same SOT-23 package family. It serves as a cost-effective solution for general-purpose precision referencing tasks where ultra-low noise or high precision are not primary constraints.
