„ ^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.
