LM4050BIM3X-5.0/NOPB

Voltage Reference Overview

The LM4050BIM3X-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in a SOT-23 package. It provides a fixed output of 5 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 30 ppm/°C. Maximum shunt current is 15 mA.

Voltage Reference Feature Summary

• Provides stable 5 V reference via shunt topology
• Ensures high precision with ±0.2% initial accuracy
• Optimized for low power consumption applications

Voltage Reference Applications

• Portable battery-powered instrumentation
• Handheld meters
• Data acquisition systems

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance. Confirm the operating temperature range matches the application requirements, as this variant is rated for -40°C to +85°C. Ensure the SOT-23 package dimensions fit the PCB layout constraints.

Voltage Reference Selection Notes

Select this component when a compact, low-power 5 V reference is required. The ±0.2% accuracy suits precision analog circuits. Consider the 30 ppm/°C drift for thermal stability needs. Verify that the 15 mA maximum current capability meets the circuit's load requirements.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt references. It serves as a drop-in replacement for older LM4040 devices in many designs, offering improved accuracy and lower power consumption while maintaining the same SOT-23 footprint.

Voltage Reference Replacement Considerations

LM4050BIM3-5.0/NOPB is a direct equivalent without the reel suffix.
