LM4132EMF-3.0/NOPB

Voltage Reference Overview

The LM4132EMF-3.0/NOPB is a precision series voltage reference IC manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It provides a fixed output voltage of 3 V with an initial accuracy of ±0.5%. The device operates within an input voltage range of 3.4 V to 5.5 V and supports a maximum shunt current of 20 mA. Key electrical characteristics include a temperature coefficient of 30 ppm/°C and a typical supply current of 60 µA, with a maximum of 100 µA. It features a shutdown enable function and operates reliably across a junction temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

• Integrated shutdown enable pin for power management control
• Low noise performance suitable for sensitive analog circuits
• Compact SOT-23-5 footprint for space-constrained designs

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance as per manufacturer standards. Confirm the package marking and pinout alignment with the official datasheet before integration. Ensure the ordering quantity matches the available reel or cut tape formats provided by distributors. Cross-reference the date code and lot number against quality documentation if required for critical applications.

Voltage Reference Selection Notes

Select this component when a 3 V reference with ±0.5% initial accuracy is required in a small SOT-23-5 package. It is appropriate for designs prioritizing low quiescent current and integrated shutdown functionality. Consider alternative accuracy grades, such as the AMFX variant for 0.05% tolerance, if tighter initial error margins are necessary for the specific application requirements.
