Description
The FAN1537 provides 2 output voltages: 3.3V, and either adjustable or 2.5V or 1.8V fixed with 1.0A each output current capability. These devices have been optimized for low voltage where transient response and minimum input voltage are critical.

Features
• Low dropout voltage
• Load regulation: 0.05% typical
• On-chip thermal limiting
• SO-8 and 5-lead SPAK and TO-252 DPAK packages
• Fixed 3.3V, and adjustable or 2.5V or 1.8V fixed
• Stable with low ESR output capacitors

Applications
• Hard Disk Drives, CD-ROMs, DVDs
• High efficiency linear regulators
• Post regulators for switching supplies
• ADSL and Cable Modems
• 5V to 3.3V and 2.5V linear regulators
• Motherboard with multiple supplies
