The AIC1086 is a low dropout three-terminal

regulator designed to provide output current up

to 1.5A. The device is available in an adjustable

version and fixed output voltage of 1.8V, 2.5V,

2.85V,

3.3V

and

5V.

Dropout

voltage

of

maximum of 1.5V is guaranteed at 1.5A output

current. The quality of low dropout voltage and

fast transient response make this device ideal

for low voltage microprocessor applications.

The AIC1086 requires output capacitance of a

minimum of 10

μF for stability. Built-in output

current limiting and thermal limiting provide

maximal protection to the AIC1086 against fault

conditions.
