GENERAL DESCRIPTION
TThhee _{AMS2910 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 AMS2910 devices are pin compatible with other three-terminal regulators and are offered in the 3 lead TO-220 package,
in the 3Lead TO-263 (Plastic DD), in the TO-252 (D PAK) and in the low profile surface mount SOT-223 package.
