GENERAL DESCRIPTION

The

The AMS1084 series of adjustable and fixed voltage regulators are designed to provide 5A output current and to operate

down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.5V at maximum output

current, decreasing at lower load currents.

On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload

conditions on both the regulator and power source circuitry.

The AMS1084 devices are pin compatible with older three-terminal regulators and are offered in 3 lead TO-220 package and

3 and 2 lead TO-263 (Plastic DD).
