FAN1587AM15X

Special Purpose Regulators Overview

The FAN1587AM15X is a fixed-output low dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor, designed for low-voltage microprocessor applications. It provides a regulated 1.5 V output with a maximum continuous current of 3 A. The device accepts an input voltage up to 18 V and operates within a temperature range of 0°C to +125°C. Key electrical specifications include a maximum dropout voltage of 1.3 V at full load, a typical load regulation of 0.05%, and a line regulation of 0.2%/V. It features trimmed current limiting and fast transient response capabilities.

Special Purpose Regulators Feature Summary

• Optimized for low-voltage microprocessor power supply requirements
• Provides fast transient response to dynamic load changes
• Features internally trimmed current limit protection
• Delivers stable regulation with low dropout characteristics

Special Purpose Regulators Applications

• Low voltage microprocessor core power supplies
• Point-of-load regulation in embedded systems
• Power management for portable electronic devices

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm the specific suffix indicates the 1.5 V fixed output variant. Check for RoHS compliance status as historical records may vary. Ensure the TO-263-3 package matches your PCB footprint requirements before finalizing procurement decisions.

Special Purpose Regulators Selection Notes

Select this component when a stable 1.5 V rail is required for processor cores operating under 18 V input limits. Consider the 3 A current capacity against peak processor demand. Evaluate thermal dissipation needs given the 1.3 V dropout at maximum load. Compare load regulation performance against system tolerance requirements for sensitive digital logic circuits.

Special Purpose Regulators Part Context

This part belongs to the FAN1587A series of LDO regulators from Fairchild Semiconductor, now part of onsemi. The series includes variants with different fixed output voltages such as 3.3 V and adjustable versions. These regulators are engineered specifically for high-current, low-noise applications typical in modern computing hardware.

Special Purpose Regulators Replacement Considerations

Direct substitutes include other FAN1587A variants with identical pinouts but different output voltages if system design allows. Cross-reference with onsemi's current portfolio for updated revisions. Verify thermal performance and package compatibility when considering alternative manufacturers' LDOs.
