n TYPICAL APPLICATION CIRCUIT
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. Dropout 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. Internal current
and thermal limiting provides protection
against any overload condition that would
create excessive junction temperatures.
