The AMS1117 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 1.3V 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, in the 8L SOIC package and in the TO-252 (DPAK) plastic package。
