LM4132EMF-2.5/NOPB

Voltage Reference Overview

The LM4132EMF-2.5/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.5%. The device features a temperature coefficient of 30 ppm/°C and supports a maximum input voltage of 5.5 V. It operates within a junction current range up to 20 mA and maintains functionality across an extended temperature range from -40°C to +125°C.

Voltage Reference Feature Summary

• Provides stable series voltage reference output
• Includes shutdown enable functionality for power management
• Designed for low-power applications with minimal quiescent current

Voltage Reference Applications

• Portable instrumentation requiring precise voltage standards
• Battery-powered measurement systems
• Data acquisition channels needing stable reference sources

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the 'E' designation corresponds to the specified operating temperature range and package variant. Ensure the ordering part number matches the required output voltage and accuracy grade before procurement to avoid functional mismatches.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside moderate precision levels. It is suitable for designs where power consumption must be minimized but high-speed transient response is not critical. Compare against higher accuracy variants if tighter tolerance specifications are necessary for the target application.

Voltage Reference Part Context

This device belongs to the LM4132 family of micropower shunt voltage references. It shares architectural similarities with other members like the LM4132AMF and LM4132DQ1 series, differing primarily in accuracy grades and automotive qualification status. The EMF suffix denotes the standard commercial grade version in a small outline transistor package.
