Description

AMS2911 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate 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 AMS2911 devices are pin compatible with other three-terminal regulators and are offered in the 3 lead TO-220 package, in the 3 lead TO-263 (Plastic DD) package, in the TO-252(DPAK) package and in the low profile surface mount SOT-223 package.
