REF4132B50DBVR

Overview

The REF4132B50DBVR is a low-drift, low-power series voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.05%. The device features a temperature coefficient of 12 ppm/°C and operates within an input voltage range of 3.05 V to 5.5 V. It is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Low-noise performance suitable for precision analog circuits
• Compact SOT-23-5 footprint for space-constrained designs

Applications

• Automotive sensor signal conditioning
• Data acquisition systems requiring high stability
• Precision measurement instrumentation

Procurement Notes

Verify the specific suffix 'Q1' indicates automotive qualification status. Confirm the exact output voltage tolerance matches system requirements. Ensure the SOT-23-5 thermal characteristics are adequate for the intended application environment. Check for any recent process change notifications that may affect component specifications.

Selection Notes

Select this component when automotive certification is mandatory alongside low drift specifications. Compare against non-automotive equivalents if cost sensitivity outweighs reliability requirements. Consider the maximum input voltage limit relative to the supply rail to ensure proper regulation without exceeding absolute maximum ratings.

Part Context

This part belongs to the REF4132 family of low-drift series voltage references. It shares architectural similarities with other members like the REF4132A but offers distinct automotive qualification. The family targets applications demanding long-term stability and low noise in compact packages.
