REF200AU/2K5

Current Regulation/Management Overview

The REF200AU/2K5 is a dual current source and sink integrated circuit manufactured by Texas Instruments. It provides two independent, stable output currents of 100µA each. The device features an initial accuracy of ±0.25% and operates within an input voltage range of 2.5V to 40V. It is housed in an 8-SOIC package with a width of 3.90mm. The component supports surface mount installation and functions reliably across a temperature range of -25°C to 85°C.

Current Regulation/Management Feature Summary

• Provides dual independent current sources and sinks for precise signal conditioning
• Delivers high initial accuracy of ±0.25% for stable reference applications
• Operates with a wide input voltage range from 2.5V to 40V

Current Regulation/Management Applications

• Precision current mirror circuits
• Current sink/source biasing in analog systems
• Signal conditioning modules requiring stable low-current references

Current Regulation/Management Procurement Notes

Verify the specific suffix /2K5 to confirm tape-and-reel packaging configuration. Confirm RoHS3 compliance status as indicated in official documentation. Check for Obsolescence Notices (PCN) regarding the REF200 series, as availability may be limited or subject to last-time buy constraints. Ensure the 8-SOIC footprint matches the target PCB design before procurement.

Current Regulation/Management Selection Notes

Select this component when dual, matched 100µA current outputs are required with tight initial tolerance. The 8-SOIC package suits space-constrained surface-mount designs. Consider the ±0.25% accuracy requirement against application needs. Verify that the 2.5V to 40V input range aligns with the system power supply architecture. Evaluate thermal performance within the -25°C to 85°C operating window.
