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 AMS1085 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.
