... 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 AMS1084 devices are pin compatible with older three-terminal regulators and are offered in 3 lead TO-220 package and 3 and 2 lead TO-263 (Plastic DD). ...
