AIC1084
5A Low Dropout Positive Adjustable Regulator
n FEATURES
l Dropout Voltage 1.3V at 5A Output Current.
l Fast Transient Response.
l Extremely Tight Line and Load Regulation.
l Current Limiting and Thermal Protection.
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 AIC1084 is a low dropout three terminal
regulator with 5A output current capability. The
output voltage is adjustable with the use of a
resistor divider or fixed 3.3V. Dropout voltage is
guaranteed to be at maximum of 1.4V with the
maximum output current. Its low dropout voltage
and fast transient response make it ideal for low
voltage microprocessor applications. Current limit
and thermal protection provide protection against
any overload condition that would create excessive
junction temperatures.
