Data Sheet
3-TERMINAL ADJUSTABLE REGULATOR
General Description
The AZ317L is an adjustable 3-terminal positive volt-
age regulator capable of supplying 100mA over a 1.2V
to 12V output range. This voltage regulator is excep-
tionally easy to use and requires only two external
resistors to set the output voltage. Both line and load
regulation are better than standard fixed regulators.
In addition to higher performance than fixed regula-
tors, AZ317L employs overload protection. Included
on the chip are current limiting and thermal overload
protection. All overload protection circuitry remains
fully functional even when the adjustment terminal is
disconnected.
The AZ317L is available in standard TO-92 and SOIC-
8 packages.
