DESCRIPTION
The AIC1187 is an ultra low dropout and high performance linear regulator with 1A output current capability. The output voltage is fixed 1.5V, 1.8V, 2.5V and 3.3V. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. 

In addition, the enable pin reduces power dissipation at shutdown mode. Current limit and thermal protection provide protection against any overload condition that would create excessive junction temperatures.
