LDO - AMS1117-3.3
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 different ial. 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 comp atible 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.
