3-TERMINAL ADJUSTABLE REGULATOR
AZ317L
General Description
Features
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.

·
Adjustable Output Down to 1.2V
Guaranteed 100mA Output Current
Output Short Circuit Protected
Line Regulation: 0.01%/V
Load Regulation: 0.1%
Constant Current Limit over Temperature
Standard 3-lead Transistor Package
Input Ripple Rejection: 70dB
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 Applications
fully functional even when the adjustment terminal is
disconnected.
