General Description
The AZ1117 is a series of low dropout three-terminal
regulators with a dropout of 1.15V at 1A output cur-
rent.
The AZ1117 series provides current limiting and ther-
mal 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 shut-
down provides protection against any combination of
overload and ambient temperature that would create
excessive junction temperature.
The AZ1117 has an adjustable version, that can pro-
vide the output voltage from 1.25V to 12V with only 2
external resistors.
The AZ1117 series is available in the industry standard
SOT-223, SOT-89-3, TO-220-3, TO-252-2 and TO-
263-3 power packages.
