General Description
The AZ1117B is a low dropout three-terminal regula-
tor.
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 1.2V, 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 AZ1117B is available in the industry-standard
SOT-223, TO-252-2 (1), TO-252-2 (3) and SOT-89
power packages.
