GENERAL DESCRIPTION
The AMS1083 series of adjustable and fixed voltage regulators are designed to provide 8A output current and to operate
The
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).
