GENERAL DESCRIPTION

The AMS1587 series of adjustable and fixed voltage regulators are designed to provide 3A output current and to operate

down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V 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 AMS1587 devices are pin compatible with older three-terminal regulators and are offered in 3 lead TO-220 package, 3

and 2 lead TO-263 (Plastic DD) and TO-252 (D PAK) package.
