AIC1086
1.5A Low Dropout Positive Regulator
 ^FEATURES
 ^DESCRIPTION
 Dropout Voltage 1.3V at 1.5A Output Current.
 Fast Transient Response.
 Line Regulation, typical at 0.015%.
 Load Regulation, typical at 0.1%.
 Current Limiting and Thermal Protection.
 Adjustable Output Voltage or Fixed at 1.8V, 2.5V,
2.85V, 3.3V, and 5V.
 Standard 3-Pin Power Packages.
 ^APPLICATIONS
The AIC1086 is a low dropout three-terminal
regulator designed to provide output current up
to 1.5A. The device is available in an adjustable
version and fixed output voltage of 1.8V, 2.5V,
2.85V, 3.3V and 5V. Dropout voltage of
maximum of 1.5V is guaranteed at 1.5A output
current. The quality of low dropout voltage and
fast transient response make this device ideal
for low voltage microprocessor applications.
 Post Regulator for Switching Supply.
 Battery Chargers.
 PC Add-On Card.
The AIC1086 requires output capacitance of a
minimum of 10μF for stability. Built-in output
current limiting and thermal limiting provide
maximal protection to the AIC1086 against fault
conditions.
