DESCRIPTION/ORDERING INFORMATION  
The LM317L is an adjustable three-terminal positive-voltage regulator capable of supplying 100 mA over an  
output-voltage range of 1.2 V to 32 V. It is exceptionally easy to use and requires only two external resistors to  
set the output voltage.  
In addition to higher performance than fixed regulators, this regulator offers full overload protection, available  
only in integrated circuits. Included on the chip are current-limiting and thermal-overload protection. All  
overload-protection circuitry remains fully functional even when ADJUSTMENT is disconnected. Normally, no  
capacitors are needed unless the device is situated far from the input filter capacitors, in which case an input  
bypass is needed. An optional output capacitor can be added to improve transient response. ADJUSTMENT can  
be bypassed to achieve very high ripple rejection, which is difficult to achieve with standard three-terminal  
regulators.  
In addition to replacing fixed regulators, the LM317L regulator is useful in a wide variety of other applications.  
Since the regulator is floating and sees only the input-to-output differential voltage, supplies of several hundred  
volts can be regulated as long as the maximum input-to-output differential is not exceeded. Its primary  
application is that of a programmable output regulator, but by connecting a fixed resistor between ADJUSTMENT  
and OUTPUT, this device can be used as a precision current regulator. Supplies with electronic shutdown can be  
achieved by clamping ADJUSTMENT to ground, programming the output to 1.2 V, where most loads draw little  
current.  
The LM317LC is characterized for operation over the virtual junction temperature range of 0°C to 125°C. The  
LM317LI is characterized for operation over the virtual junction temperature range of –40°C to 125°C.
