GENERAL DESCRIPTION
The 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-89 SOT-223 package, in the 8L SOIC package and in the TO-252 (DPAK) plastic package.
