LM4132BMF-3.0/NOPB

Voltage Reference Overview

The LM4132BMF-3.0/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a surface-mount SOT-23-5 package. It provides a fixed output voltage of 3 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 30 ppm/°C and supports a maximum input voltage of 6 V. It operates within a junction temperature range of -40°C to +125°C and draws a typical quiescent current of 60 µA. The component is RoHS compliant and designed for high-stability applications requiring low power consumption.

• Low power consumption with 60 µA operating current
• Wide operating temperature range from -40°C to +125°C
• Compact SOT-23-5 surface-mount packaging

Voltage Reference Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Industrial process control loops
• Medical equipment requiring precise voltage references

Voltage Reference Procurement Notes

Verify the specific suffix 'BMF' indicates the correct accuracy grade (0.1%) and tape-and-reel packaging configuration. Confirm RoHS compliance status matches project requirements. Ensure the SOT-23-5 footprint aligns with the PCB design. Check for any recent process change notifications that might affect pinout or electrical characteristics before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a 3 V reference with 0.1% initial accuracy is required. Compare against the EMF variant if 0.5% accuracy is sufficient for lower cost. Consider the AMF variant if tighter 0.05% accuracy is needed. Ensure the 6 V maximum input voltage meets the supply rail constraints. Verify thermal management needs for the SOT-23-5 package in enclosed environments.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower shunt voltage references. It shares the same core architecture as other LM4132 variants but differs in accuracy grades and packaging options. The BMF suffix denotes a specific binning for 0.1% accuracy and reel packaging. It serves as a drop-in replacement for older LM4132 models with compatible pinouts.

Voltage Reference Replacement Considerations

LM4132EMF-3.0/NOPB offers 0.5% accuracy. LM4132AMF-3.0/NOPB provides 0.05% accuracy. LM4132CMF-3.0/NOPB delivers 0.2% accuracy. All share the SOT-23-5 package and 3 V output.
