General Description
The AZ317 is an adjustable three-terminal positive
voltage regulator with a very low dropout of 1.2V at
1A output current. Using 2 external resistors, the
AZ317 can provide an adjustable output voltage down
to 1.25V.
The AZ317 includes a circuit of trimmed bandgap ref-
erence to assure output voltage accuracy to be within
1%. It also provides current limiting and thermal shut-
down. The current limit is trimmed to ensure specified
output current and controlled short-circuit current. The
On-chip thermal limiting provides protection against
any combination of overload and ambient temperature
that would create excessive junction temperature.
The AZ317 is available in the standard SOT-223, TO-
220, TO-252 and TO-263 power packages.
