The AZ1117C is available in 1.2V, 1.5V, 1.8V, 2.5V,
3.3V, 5.0V fixed output voltage vesions and ADJ out-
put voltage version. The fixed versions integrate the
adjust resistors. It is also available in an adjustable ver-
sion which can set the output voltage with two external
resistors.
The AZ1117C is available in the industry-standard
TO-252-2 (3), TO-252-2 (4), SOT-89 and SOT-223
power packages.
