DESCRIPTION

The AIC1117 is a low dropout three terminal regulator with 800mA output current capability. The output voltage is adjustable with the use of a resistor divider . For fixed output voltage versions, the output voltage is internally set at 2.85V, 3.3V or 5V. D ropout is guaranteed at a maximum of 1.3V at maximum output current. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. I nternal current and thermal limiting provides pr otection against any overload condition that would create excessive junction te mperatures.
