Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the package designation matches the required SOT-23-5 footprint for PCB layout compatibility. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits to maintain rated performance and longevity.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with ±0.2% initial accuracy is required in a small form factor. It is suitable for applications demanding low quiescent current and precise voltage stability over temperature variations. Consider the 20 mA maximum output current capability to ensure adequate drive strength for downstream circuitry without exceeding thermal constraints.

Voltage Reference Part Context

This part belongs to the LM4132 family of precision low-dropout voltage references designed for space-constrained applications. The family offers various fixed output voltages and accuracy grades, all sharing similar pinouts and functional characteristics. The CMF variant specifically denotes the commercial grade temperature range and standard accuracy tier within the broader product lineup.

Voltage Reference Replacement Considerations

LM4132CMF-2.5/NOPB serves as the direct equivalent to LM4132CMF-2.5. Verify that any substitute maintains the same SOT-23-5 package and 2.5 V output voltage. Cross-reference temperature coefficients and accuracy ratings to ensure compatibility with existing design tolerances.
