GENERAL DESCRIPTION

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.

conditions on both the regulator and power source circuitry.

The AMS1082 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).

PIN CONNECTIONS

FIXED VERSION

The AMS1082 series of adjustable and fixed voltage regulators are designed to provide 10A output current and to operate

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