Product Summary

The AMS1117-1.8V is an adjustable and fixed voltage regulator. It is designed to provide 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the AMS1117-1.8V 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 AMS1117-1.8V 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.
