Description

The AIC1117A is a low dropout three terminal regulator with 1A output current capability. The output voltage is adjustable with the use of a resistor divider or fixed 1.8V, 2.5V, 2.85V, 3.3V. 5V, Dropout voltage is guaranteed to be at a maximum of 1.5V with the maximum output current. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. The current limiting and thermal protection provide protection against any overload condition that would create excessive junction temperatures.
