3-TERMINAL 1A ADJUSTABLE VOLTAGE REGULATOR
AZ317
General Description
Features
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.

Trimmed Current Limit
On-chip Thermal Protection
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.

Since IADJ is controlled to less than 100μA, the error associated with this term is negligible
in most applications.
