n DESCRIPTION
The AIC1086 is a low dropout three terminal regulator with 1.5A output current capability. The output voltage is adjustable with the use of a resistor divider or fixed 2.85V, 3.3V, 5V. Dropout is guaranteed at a maximum of 1.5V 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.
Dropout Voltage 1.3V at 1.5A Output Current. Fast Transient Response. Line Regulation typically at 0.015%. Load Regulation typically at 0.1%. Internal Thermal and Current Limiting. Adjustable Output Voltage or Fixed 2.85V, 3.3V, 5V. Standard 3-Pin Power Packages.
