AMS1117系列芯片手册

GENERAL DESCRIPTION The AMS1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operatedown to IV input-to-output differential. The dronout voltage of the device is guaranteed maximum 13V 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 surfaco mount SOT-223 package, in the 8L SOIC package and in the TO-252 (DPAK) plastic package.
