LM4050BIM3X-5.0/NOPB

Voltage Reference Overview

The LM4050BIM3X-5.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output of 5V with an initial accuracy of ±0.2% and a temperature coefficient of 50ppm/°C. The device operates within a cathode current range up to 15mA and supports a supply voltage from 2.5V to 40V. It functions in an ambient temperature range of -40°C to +85°C and is housed in a compact SOT-23 surface-mount package.

Voltage Reference Feature Summary

• Micropower operation designed for battery-powered applications
• High precision with tight initial tolerance specifications
• Compact three-terminal SOT-23 surface-mount packaging

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Battery-operated measurement systems
• Data acquisition systems needing stable reference voltages

Voltage Reference Procurement Notes

Verify the component status as this specific part number may be discontinued or subject to limited availability. Confirm that the suffix NOPB indicates lead-free compliance and RoHS adherence. Ensure the supplier source is authorized to guarantee authenticity, as counterfeit references can compromise circuit accuracy. Check for alternative revisions if original stock is unavailable.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference with high accuracy is required in space-constrained designs. The SOT-23 package suits automated surface-mount assembly processes. Consider the operating temperature range limits for harsh environments. Evaluate the quiescent current requirements against system power budgets to ensure efficient operation during standby modes.

Voltage Reference Part Context

This device belongs to the LM4050 series of micropower shunt voltage references. It serves as a drop-in replacement for older discrete zener diode solutions, offering superior stability and lower noise. The series is widely used in industrial and consumer electronics where precise voltage regulation is critical for analog signal processing and ADC/DAC inputs.
