LM4050BIM3-2.5

Voltage Reference Overview

The LM4050BIM3-2.5 is a micropower shunt voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of ±0.2%. Packaged in a compact SOT-23-3 surface-mount format, it operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100 ppm/°C. The device supports a maximum cathode current of 15 mA and requires a minimum operating current of 65 µA.

Voltage Reference Feature Summary

• Provides stable precision voltage regulation via a shunt topology
• Designed for low-power applications with micropower consumption characteristics
• Engineered for reliable operation across extended industrial temperature ranges

Voltage Reference Applications

• Portable instrumentation requiring precise voltage references

Voltage Reference Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required tolerance and package variant. Check for recent discontinuance notifications or process change notices that may affect long-term availability. Ensure compliance with RoHS directives relevant to the target market.

Voltage Reference Selection Notes

Select this component when a fixed 2.5 V reference with ±0.2% initial accuracy is required. It is suitable for designs needing operation up to +85°C. Consider the 100 ppm/°C temperature coefficient against stricter drift requirements. Evaluate the 15 mA maximum current capability against load demands.

Voltage Reference Part Context

This part belongs to the LM4050-N series of precision micropower shunt voltage references. It complements other variants like the LM4050CEM3-2.5 which offers different accuracy grades. The series provides options for various automotive and industrial applications using standard SOT-23 packaging.

Voltage Reference Replacement Considerations

LM4050QBIM3-2.5/NOPB: Offers higher automotive qualification (AEC-Q100) and extended temperature range up to +125°C while maintaining similar electrical characteristics.
