3-TERMINAL ADJUSTABLE REGULATOR
AZ317L
General Description
Features
The AZ317L is an adjustable 3-terminal positive voltage regulator capable of supplying 100mA over a 1.2V
to 12V output range. This voltage regulator is exceptionally 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 regulators, 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.
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
