TSM6025BEUR+T

Overview

The TSM6025BEUR+T is a precision, low-power, low-dropout series-mode voltage reference manufactured by Silicon Labs. It provides a fixed output of +2.5V with an initial accuracy of 0.4% (max). The device features a maximum temperature coefficient of 25ppm/°C and a quiescent supply current of 35μA (max). It operates within an input voltage range of 2.7V to 12.6V and supports load currents up to ±500μA. The component is housed in a SOT-23-3 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Pin-for-pin compatible alternate source for the MAX6025 voltage reference
• Series-mode architecture ensures supply current remains unaffected by input voltage changes
• Output stage stability maintained for capacitive loads up to 2200pF
• Capable of sourcing and sinking load currents up to 500μA

Applications

• Portable battery-powered instrumentation systems
• Precision data acquisition circuits requiring stable reference voltages
• Low-power sensor interface applications
• Calibration equipment utilizing series-mode references

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm that the 'B' grade designation corresponds to the 0.4% initial accuracy specification rather than the 'A' grade variant. Ensure compatibility with existing PCB footprints designed for SOT-23-3 packages. Check for any recent product change notices regarding manufacturing location or material composition updates.

Selection Notes

Select this component when a 2.5V reference with 0.4% accuracy is sufficient for the application requirements. Consider the 25ppm/°C temperature coefficient for thermal stability needs. Evaluate the 35μA quiescent current against system power budgets. Verify that the 2.7V minimum input voltage aligns with the available supply rails. Compare against the 'A' grade version if tighter initial accuracy is required.

Part Context

This part belongs to the TSM6025 family of precision voltage references from Silicon Labs. It serves as a direct replacement for Maxim Integrated's MAX6025. The family includes variants with different accuracy grades, such as the TSM6025A with 0.2% accuracy. These devices are designed for applications demanding high precision and low power consumption in compact surface-mount packages.

Replacement Considerations

The TSM6025AEUR+T is a verified substitute offering higher initial accuracy (0.2%) but shares the same pinout and form factor.
