LM4050BIM3X-2.0/NOPB

Voltage Reference Overview

The LM4050BIM3X-2.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.048 V. It features an initial accuracy of 0.2% and a temperature coefficient of 30 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum cathode current of 15 mA with a minimum operating current of 65 µA. Packaged in a surface-mount SOT-23 (SC-70) case, it is supplied in tape and reel format for automated assembly.

Voltage Reference Feature Summary

• Provides stable 2.048 V reference via shunt regulation architecture
• Maintains high precision with 0.2% initial accuracy tolerance
• Ensures thermal stability through low 30 ppm/°C temperature coefficient
• Optimized for battery-powered systems with ultra-low quiescent current

Voltage Reference Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement devices
• Data acquisition systems
• Handheld meters

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free/RoHS compliance status as per manufacturer documentation. Confirm the 'X' designation corresponds to the tape and reel packaging variant rather than cut tape. Ensure the ordering part number matches the required accuracy grade and package type for your design implementation.

Voltage Reference Selection Notes

Select this component when a 2.048 V reference is required with tight 0.2% accuracy and low drift. It is suitable for designs needing minimal power consumption due to its low operating current. Compare against the LM4040 series if higher temperature coefficients are acceptable or different voltage options are needed.

Voltage Reference Part Context

This device belongs to the LM4050-N family of micropower shunt voltage references. It shares the same pinout and form factor as other variants in the series but offers specific performance characteristics including 0.2% accuracy and 30 ppm/°C drift. It serves as a compact solution for space-constrained applications requiring reliable voltage referencing.

Voltage Reference Replacement Considerations

LM4050BIM3-2.0/NOPB is the non-reel equivalent. LM4050AIM3X-2.0/NOPB offers tighter 0.1% accuracy. LM4040CIM3X-2.0/NOPB provides 0.5% accuracy with higher drift.
