AIC1085  
3A LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR  
SPEC NO: DS-1085-01 FEB 02, 01  
nFEATURES  
nDESCRIPTION  
l Dropout Voltage 1.3V at 3A Output Current.  
l Fast Transient Response.  
The AIC1085 is a low dropout three terminal  
regulator with 3A output current capability. The  
output voltage is adjustable with the use of a resistor  
divider or fixed 1.5V, 1.8V, and 3.3V. Dropout is  
l Extremely Tight Line and Load Regulation.  
l Internal Thermal and Current Limiting.  
l Adjustable Output Voltage or Fixed 1.5V, 1.8V,  
guaranteed at a maximum of 1.4V at maximum  
output current. Its low dropout voltage and fast  
transient response make it ideal for low voltage  
microprocessor applications. Internal current and  
thermal limiting provides protection against any  
overload condition that would create excessive  
junction temperatures.  
3.3V.  
l Standard 3-Pin Power Packages.  
nAPPLICATIONS  
l Mother Board I/O Power Supplies.  
l Microprocessor Power Supplies.  
l High Current Regulator.  
l Post Regulator for Switching Supply.
