LM4132CMF-3.0/NOPB

Voltage Reference Overview

The LM4132CMF-3.0/NOPB is a precision series voltage reference manufactured by Texas Instruments, housed in a compact SOT-23-5 surface-mount package. It provides a fixed output voltage of 3 V with an initial accuracy of 0.05% and a temperature coefficient of 20 ppm/°C. The device supports a maximum input voltage of 6 V and can handle a maximum shunt current of 20 mA. It operates within a wide temperature range from -40°C to +125°C and features a shutdown enable function.

Voltage Reference Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature drift characteristics for stable performance across varying thermal conditions
• Includes a dedicated shutdown enable pin for power management control

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Data acquisition systems needing precise voltage references

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the 'CMF' designation corresponds to the correct accuracy grade and temperature range for your application requirements. Ensure the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a 3 V reference with 0.05% initial accuracy is required in a small form factor. Consider the 20 ppm/°C temperature coefficient for applications sensitive to thermal variations. The 20 mA maximum shunt current capability allows for moderate load driving without external buffering in many standard configurations.

Voltage Reference Part Context

This part belongs to the LM4132 family of precision shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades, all sharing the same SOT-23-5 package and low-power architecture. The CMF variant specifically denotes the 0.05% accuracy class within this series.

Voltage Reference Replacement Considerations

LM4132CMF-3.0/NOPB serves as the direct non-packaging-free equivalent to LM4132CMF-30-NOPB. Verify pinout compatibility and electrical specifications against alternative precision references if sourcing constraints require substitution.
