AIC1086

1.5A Low Dropout Positive Regulator

FEATURES

DESCRIPTION



Dropout Voltage 1.3V at 1.5A Output Current.

Fast Transient Response.

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.



Line Regulation, typical at 0.015%.

Load Regulation, typical at 0.1%.

Current Limiting and Thermal Protection.

Adjustable Output Voltage or Fixed at 1.8V, 2.5V,

2.85V, 3.3V, and 5V.

Standard 3-Pin Power Packages.



APPLICATIONS



Post Regulator for Switching Supply.

Battery Chargers.



The AIC1086 requires output capacitance of a

minimum of 10μF for stability. Built-in output

current limiting and thermal limiting provide

maximal protection to the AIC1086 against fault

conditions.

PC Add-On Card.
