description  
The LM317 is an adjustable three-terminal  
positive-voltage regulator capable of supplying  
more than 1.5 A over an output-voltage range of  
1.2 V to 37 V. It is exceptionally easy to use and  
requires only two external resistors to set the  
output voltage. Furthermore, both line and load  
regulation are better than standard fixed  
regulators. The LM317 is packaged in the KC  
(TO-220AB) and KTE packages, which are easy  
to handle and use.

TheOUTPUT terminal is inelectrical  
contact with the mounting base.  
In addition to having higher performance than  
fixed regulators, this device includes on-chip  
current limiting, thermal overload protection, and  
safe-operating-area protection. All overload  
protection remains fully functional, even if the  
ADJUST terminal is disconnected.

The LM317 is versatile in its applications,  
including uses in programmable output regulation  
and local on-card regulation. Or, by connecting a  
fixed resistor between the ADJUST and OUTPUT  
terminals, the LM317 can function as a precision  
current regulator. Anoptionaloutputcapacitorcan  
be added to improve transient response. The  
ADJUST terminal can be bypassed to achieve  
very high ripple-rejection ratios, which are difficult  
to achieve with standard three-terminal  
regulators.

The LM317 is characterized for operation over the  
virtual junction temperature range of 0°C to  
125°C.
