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 1.8V, 2.5V or 3.3V. Dropout voltage is guaranteed to be at a maximum of 1.3 V with the maximum output current.
Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. Current limiting and thermal protection provide protection against any overload condition that would create excessive junction temperatures.
