LM4040CIM3X-5.0/NOPB

Overview

The LM4040CIM3X-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 5.0 V with an initial accuracy of ±0.5%. It operates within a temperature range of -40°C to +85°C and has a maximum shunt current of 15 mA. The device utilizes a SOT-23 surface-mount package.

Feature Summary

• Provides stable precision voltage reference in a compact three-pin SOT-23 package
• Designed for low-power applications with micropower consumption characteristics
• Capable of operating across extended industrial temperature ranges

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition circuits

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the 'CIM3X' designation corresponds to the correct tape-and-reel packaging format required for automated assembly processes. Ensure the component matches the original National Semiconductor or Texas Instruments specifications for pinout and electrical parameters.

Selection Notes

Select this component when a fixed 5.0 V reference with ±0.5% accuracy is required in a space-constrained design. Consider the 15 mA maximum shunt current limit for load regulation requirements. Evaluate the thermal performance within the specified -40°C to +85°C operating range for the intended environment.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040CIM3X-5.0/NOPB specifically provides a 5.0 V output in a small outline transistor package suitable for surface mount technology.

Replacement Considerations

LM4040CIM3-5.0/NOPB is a non-tape variant of the same electrical specification.
