AIC1085
3A LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR
SPEC NO: DS-1085-01 FEB 02, 01
n FEATURES
l Dropout Voltage 1.3V at 3A Output Current.
l Fast Transient Response.
l Extremely Tight Line and Load Regulation.
l Internal Thermal and Current Limiting.
l Adjustable Output Voltage or Fixed 1.5V, 1.8V,
3.3V.
l Standard 3-Pin Power Packages.
n APPLICATIONS
l Mother Board I/O Power Supplies.
l Microprocessor Power Supplies.
l High Current Regulator.
l Post Regulator for Switching Supply.
n DESCRIPTION
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
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.
