general description
tthhee ams1117 series of adjustable and fixed voltage regulators are designed to provide 800ma output current and to operate
down to 1v input-to-output differential. 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 compatible with other three-terminal scsi regulators and are offered in the low profile surface
mount sot-223 package and in the to-252 (dpak) plastic package.
