REF200AU/2K5G4

Current Regulation/Management Overview

The REF200AU/2K5G4 is a precision current mirror and sink/source regulator manufactured by Texas Instruments. It delivers a fixed output current of 100µA with an accuracy of ±0.25%. The device operates within an input voltage range of 2.5V to 40V and supports an extended operating temperature range from -25°C to 85°C. It is housed in an 8-SOIC surface-mount package, specifically the 8-SOIC (0.154 inch, 3.90mm width) supplier device package.

Current Regulation/Management Feature Summary

• Provides precise current mirroring and regulation capabilities for analog signal processing.
• Delivers stable current source and sink functionality with high initial accuracy.
• Operates reliably across a wide industrial temperature range.

Current Regulation/Management Applications

• Precision current biasing in sensor interfaces
• Current mode signal processing circuits
• Analog front-end conditioning

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized channels due to discontinued status at major distributors. Confirm RoHS3 compliance and moisture sensitivity level 3 handling requirements during storage and assembly. Validate package dimensions against design specifications to ensure compatibility with existing footprints.

Current Regulation/Management Selection Notes

Select this component when a stable 100µA reference current is required with tight tolerance constraints. Ensure the application voltage remains within the 2.5V to 40V input range. Consider the 8-SOIC package constraints for PCB layout and thermal management in dense designs.

Current Regulation/Management Part Context

This part belongs to the REF200 family of current regulators. It shares functional similarities with other TI current sources but offers specific accuracy and packaging options tailored for precision applications. The G4 suffix indicates lead-free construction compliant with environmental standards.

Current Regulation/Management Replacement Considerations

REF200AU/2K5 is a direct pin-compatible alternative. Verify electrical parameters and package dimensions before substitution.
