The Texas Instruments LM4132AQ1MFT2.5 is a series voltage reference with a fixed 2.5 V output, ±0.05% tolerance, and 20 ppm/°C drift.
The ±0.05% tolerance and 20 ppm/°C drift keep the output stable across the -40°C to 125°C range.
This removes the risk of an unplanned BOM respin for automotive programs that require multi-year supply continuity. The part is ROHS3 compliant.
The LM4132AQ1MFT2.5 is the AEC-Q100 qualified variant of the LM4132 series. The LM4132AIMFT2.5 is an industrial-temperature version; the A-grade part meets the same electrical specs but adds automotive qualification and the extended -40°C to 125°C junction temperature range. A direct replacement depends on whether the application requires AEC-Q100 documentation and the wider temperature rating.
Initial output voltage tolerance is ±0.05%, and the temperature coefficient is 20 ppm/°C over the full -40°C to 125°C range.
