　　GENERAL DESCRIPTION

　　The AMS1117 series of adjustable and fixed voltage regulators are designed to provide 800mA output current and to operate down to

　　1V input-to-output differential. 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 AMS1117 devices are pin compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount

　　SOT-223 package and in the TO-252 (DPAK) plastic package.
