FAN1538  
Dual Channel 1A Low Dropout  
Linear Regulator with UVLO and Soft-start  
Features  
General Description  
• Two independent outputs  
The FAN1538 provides two output voltages: a fixed 3.3V  
ouput and either a fixed 2.5V or adjustable output with 1A  
output current capability. Refer to Ordering Information for  
details.  
• Load regulation: 0.05% typical  
• Under-voltage lockout and softstart  
• Over Temperature protection  
• T0-252 DPAK, 5-lead SPAK packages  
• Fixed 3.3V and adjustable or fixed 2.5V output  
Current limit protects against short circuit currents and on  
chip over temperature circuitry limits the maximum die tem-  
perature.  
Applications  
• Hard Disk Drives, CD-Roms  
• Set-top Boxes  
• ADSL line cards  
Under voltage lockout and softstart circuitry protects against  
unregulated output voltages when the input voltage is below  
specification.  
• Motherboards with multiple supplies
