DESCRIPTION

The LM1084 is a low dropout three terminal

regulator with 5A output current capability. The

output voltage is adjustable with the use of a

resistor divider or fixed 1.5V, 1.8V, 2.5V, 3.3V and 5.0V.

Dropout voltage is guaranteed to be at maximum

of 1.4V with the maximum output current. Its low

dropout voltage and fast transient response make

it ideal for low voltage microprocessor applications.

Current limit and thermal protection provide

protection against any overload condition that

would create excessive junction temperatures.
