LM4050QBIM3X8.2/NOPB

Voltage Reference Overview

The LM4050QBIM3X8.2/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring an 8.192 V fixed reverse breakdown voltage with ±0.2% initial accuracy at 25°C. It operates within a wide current range of 74 μA to 15 mA and maintains a maximum temperature coefficient of 50 ppm/°C across the -40°C to 125°C extended industrial temperature range. The device utilizes a compact SOT-23 package and requires no external stabilizing capacitor for stability.

Voltage Reference Feature Summary

• Eliminates the need for external stabilizing capacitors while ensuring stability with any capacitive load
• Utilizes fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure high accuracy
• Bandgap reference temperature drift curvature correction ensures stable performance over wide operating temperatures

Voltage Reference Applications

• Portable, battery-powered equipment
• Data acquisition systems
• Instrumentation
• Process control
• Precision audio components

Voltage Reference Procurement Notes

Verify that the specific ordering suffix matches the required tolerance grade (B grade for ±0.2%) and temperature range (extended). Confirm the package type is SOT-23 and check for automotive qualification requirements if applicable to the target application environment.

Voltage Reference Selection Notes

Select this component when space-critical designs require a precise shunt reference without output capacitors. The B-grade designation provides tighter initial accuracy than standard C-grade options. Ensure the operating current remains within the specified minimum and maximum limits to maintain regulation stability.

Voltage Reference Part Context

This part belongs to the LM4050-N family of precision micropower shunt voltage references. It shares the same core architecture as other variants in the series but is specifically configured for the 8.192 V output level with B-grade accuracy specifications.
