FAN1589DX

Special Purpose Regulators Overview

The FAN1589DX is a low dropout linear regulator designed for VRM8.5 compliance, providing a fixed 1.2V output with 2.7A current capability. It features fast transient response and low dropout voltage at full load. The device includes trimmed current limit and on-chip thermal limiting protection. It is housed in a TO-252 (DPAK) package suitable for surface mount applications.

Special Purpose Regulators Feature Summary

• Optimized for VTT bus termination with fast transient response
• Integrated thermal limiting and trimmed current protection
• Fixed 1.2V output with 2.7A continuous current capability

Special Purpose Regulators Applications

• GTL+ bus supply for VRM 8.5
• Low voltage logic supply
• Post regulator for switching supplies

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'DX' against the manufacturer's official datasheet to confirm the exact package type and tape & reel specifications. Ensure compatibility with VRM8.5 standards if used in memory termination circuits. Check for RoHS compliance status in the latest documentation.

Special Purpose Regulators Selection Notes

Select this component when a fixed 1.2V output with high current drive is required for GTL+ applications. Consider the TO-252 package for surface mount constraints. Evaluate thermal performance requirements given the 2.7A output capability and dropout characteristics.
