The AMS1117 series of adjustable and fixed voltage regulators are designed to provide up to1A output current and to operate down  to  1V  input-to-output  differential.  The  dropout  voltage  of  the  device  is  guaranteed  maximum  1.3V,  decreasing  at  lower load currents.  On-chip  trimming  adjusts  the  reference  voltage  to 1.5%.  Current limit is set to minimize 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

Applications:

• High Efficiency Linear Regulators
