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.
