TSM6025AEUR+T

Overview

The TSM6025AEUR+T is a precision, low-power, series-mode voltage reference manufactured by Silicon Labs. It provides a fixed +2.5V output with an initial accuracy of 0.2% maximum and a temperature coefficient of 15ppm/°C maximum. The device operates within a supply voltage range of VOUT + 0.2V to 12.6V and draws a quiescent current of 35μA maximum. It features a dropout voltage of 100mV at a 500μA load and can source or sink up to ±500μA. The component is stable with capacitive loads up to 2200pF and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Pin-for-pin alternate source for the MAX6025 voltage reference
• Low power consumption with minimal supply current change relative to input voltage variations
• Capacitive-load stability without requiring external compensation components
• Integrated bandgap reference architecture ensuring high thermal stability

Applications

• Industrial and Process-Control Systems
• Data Acquisition Systems
• Battery-Operated Equipment
• Precision 3V/5V Systems

Procurement Notes

Verify that the specific part number matches the required grade (TSM6025A) and package configuration (SOT-23). Confirm the manufacturer is Silicon Labs, as this component serves as an alternate source for Maxim Integrated parts. Ensure the ordering suffix corresponds to the desired carrier quantity and packaging type. Cross-reference datasheet specifications against system requirements before finalizing procurement.

Selection Notes

Select the TSM6025AEUR+T when a precise 2.5V reference is needed in space-constrained designs. Its low quiescent current makes it suitable for battery-powered applications. The wide input voltage range allows flexibility in power supply design. Verify that the application does not require higher accuracy grades or wider operating temperature ranges than those specified for the 'A' grade.

Part Context

This component belongs to the TSM6025 family of precision voltage references produced by Silicon Labs. It is designed as a direct replacement for the Maxim Integrated MAX6025, maintaining identical pinouts and electrical characteristics. The series includes variants such as the TSM6025B, which offers slightly lower accuracy but similar functionality. These devices are widely used in analog signal conditioning circuits.

Replacement Considerations

The TSM6025AEUR+T is explicitly documented as a pin-for-pin alternate source for the MAX6025AEUR+T. Designers replacing these components should verify that the original design accommodates the slight differences in long-term stability and noise characteristics if applicable.
