REF5025IDGKT

Overview

The REF5025IDGKT is a precision series voltage reference manufactured by Texas Instruments, housed in an 8-VSSOP surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy tolerance of ±0.05%. The device features a low temperature coefficient of 3 ppm/°C and operates within an input voltage range of 2.7 V to 18 V. It draws a supply current of 1.2 mA and supports a maximum load current of 10 mA. The component functions reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Exhibits very low drift characteristics suitable for sensitive measurement applications
• Operates efficiently with low quiescent current consumption

Applications

• Medical equipment requiring stable reference voltages
• Data acquisition systems demanding high accuracy
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix IDGKT to confirm the 8-VSSOP package and reel packaging configuration. Ensure compatibility with standard surface-mount assembly processes. Confirm that the 2.7 V minimum input voltage aligns with your system power rails. Validate that the 125°C maximum operating temperature meets your environmental requirements. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when precise long-term stability and low noise are critical. The 3 ppm/°C drift rate makes it superior to general-purpose references. Consider the 8-VSSOP footprint for space-constrained designs. Compare against higher accuracy variants like the E-series if tighter tolerances are needed. Evaluate the 1.2 mA supply current against battery life constraints in portable devices.
