LM4132DMF-3.0/NOPB

Voltage Reference Overview

The LM4132DMF-3.0/NOPB is a precision series voltage reference manufactured by Texas Instruments, which acquired National Semiconductor. It provides a fixed output of 3.0V with an initial accuracy of 0.5%. The device operates within an input voltage range of 3.7V to 5.5V and supports a maximum shunt current of 20mA. It features a temperature coefficient of 30ppm/°C and consumes 60µA of supply current. The component is housed in a SOT-23-5 package and functions across a temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Integrated shutdown enable functionality for power management
• Low dropout operation suitable for battery-powered applications
• High precision stability with low temperature drift

Voltage Reference Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement systems
• Data acquisition systems needing stable reference voltages

Voltage Reference Procurement Notes

Verify the manufacturer designation as Texas Instruments due to the acquisition of National Semiconductor. Confirm the specific suffix 'NOPB' indicates lead-free and RoHS compliance. Ensure the SOT-23-5 package matches the design footprint requirements. Cross-reference the datasheet for the latest electrical characteristics and thermal specifications before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a 3.0V fixed reference with 0.5% initial accuracy is required. Consider the 30ppm/°C temperature coefficient for thermal stability needs. Evaluate the 20mA maximum shunt current against load requirements. The SOT-23-5 package is suitable for space-constrained surface-mount designs.

Voltage Reference Part Context

This part belongs to the LM4132 family of precision micropower shunt voltage references. It shares architectural similarities with other variants in the series, differing primarily in output voltage and accuracy grades. The device is designed for applications demanding high stability and low power consumption in compact packages.

Voltage Reference Replacement Considerations

LM4132EMF-3.0/NOPB offers higher accuracy (0.05%) with identical voltage and package. LM4132AMF-3.0/NOPB provides even tighter tolerance (0.05%). Verify pinout compatibility and thermal performance when substituting.
