The AZ1117 is a series of low dropout three-terminal regulators with adropout of 1.15V at 1A output current.The AZ1117 series provides current limiting and thermal shutdown.Its circuit includes a trimmed bandgap reference to assure outputvoltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V,5.0V and adjustable versions or 2% for 1.2V version. Current limit istrimmed to ensure specified output current and controlled short-circuitcurrent. On-chip thermal shutdown provides protection against anycombination of overload and ambient temperature that would createexcessive junction temperature.The AZ1117 has an adjustable version, which can provide the outputvoltage from 1.25V to 12V with only 2 external resistors.The AZ1117 series is available in the industry standard SOT223,SOT89, TO220-3, TO252-2 (3), TO252-2 (4), TO252-2 (5) and TO263power packages.
