800ma low dropout voltage  regulatorams1117
general description
the  the 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。
