GENERAL DESCRIPTION

The The AMS1083 series of adjustable and fixed voltage regulators are designed to provide 8A 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 AMS1083 devices are pin compatible with older three-terminal regulators and are offered in 3 lead TO-220 package and 3 lead TO-263 (Plastic DD).
