LM4132BMF-2.5/NOPB

Voltage Reference Overview

The LM4132BMF-2.5/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a surface-mount SOT-23-5 package. It provides a fixed nominal output voltage of 2.5 V with an initial accuracy of ±0.1%. The device operates within a temperature range of -40°C to +125°C and features a maximum shunt current of 20 mA. Key electrical specifications include a maximum input voltage of 6 V, a typical quiescent current of 60 µA, and a line regulation of 50 ppm/V.

Voltage Reference Feature Summary

• Provides stable fixed voltage reference output
• Features low power consumption for battery applications
• Includes shutdown enable functionality

Voltage Reference Applications

• Portable instrumentation systems
• Data acquisition circuits
• Battery-powered measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm the 'BMF' designation corresponds to the required ±0.1% initial accuracy grade and 2.5 V output voltage. Ensure the SOT-23-5 package footprint matches the target PCB layout constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when high precision is required alongside minimal power usage in compact designs. The ±0.1% accuracy suits applications demanding tight tolerance without complex calibration. The low operating current makes it suitable for energy-constrained environments where standard references would deplete batteries too quickly.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades within the same SOT-23-5 form factor. The BMF variant specifically targets applications requiring tighter initial accuracy compared to lower-grade options in the same series.

Voltage Reference Replacement Considerations

LM4132BMF-2.5 (without NOPB suffix) serves as a direct functional equivalent if lead-free certification is not strictly mandated.
