GENERAL DESCRIPTION

The The AMS1585 series of adjustable and fixed voltage regulators are designed to provide 4.6A output current and to operate down to 1.35V input-to-output differential 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 AMS1585 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).
