The AZ1117 is a series of low dropout three-terminal regulators with a dropout 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 output  voltage 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 is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature.
