SOT-223
General Description
The AZ1117B is a low dropout three-terminal regula-
tor with a dropout of 1.2V at 800mA output current.
The AZ1117B has been optimized for low voltage
where transient response and minimum input voltage
are critical. It provides current limit and thermal shut-
down. Its circuit includes a trimmed bandgap reference
to assure output voltage accuracy to be within
1%.
On-chip thermal shutdown provides protection against
a combination of high current and ambient temperature
that would create excessive junction temperature.
The AZ1117B is available in 1.8V, 2.5V and 3.3V ver-
sions. The fixed versions integrate the adjust resistors.
It is also available in an adjustable version which can
set the output voltage with two external resistors.
The AZ1117B is available in the industry-standard
SOT-223 power package.

Absolute Maximum Ratings (Note 1)
Note 1:
Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
