LM117/LM317A/LM317  
3-Terminal Adjustable Regulator  
the maximum input to output differential is not exceeded, i.e.,  
avoid short-circuiting the output.  
General Description  
The LM117 series of adjustable 3-terminal positive voltage  
regulators is capable of supplying in excess of 1.5A over a  
1.2V to 37V output range. They are exceptionally easy to use  
and require only two external resistors to set the output volt-  
age. Further, both line and load regulation are better than  
standard fixed regulators. Also, the LM117 is packaged in  
standard transistor packages which are easily mounted and  
handled.  
Also, it makes an especially simple adjustable switching reg-  
ulator, a programmable output regulator, or by connecting a  
fixed resistor between the adjustment pin and output, the  
LM117 can be used as a precision current regulator. Supplies  
with electronic shutdown can be achieved by clamping the  
adjustment terminal to ground which programs the output to  
1.2V where most loads draw little current.  
For applications requiring greater output current, see LM150  
series (3A) and LM138 series (5A) data sheets. For the neg-  
ative complement, see LM137 series data sheet.  
In addition to higher performance than fixed regulators, the  
LM117 series offers full overload protection available only in  
IC's. Included on the chip are current limit, thermal overload  
protection and safe area protection. All overload protection  
circuitry remains fully functional even if the adjustment termi-  
nal is disconnected.

Guaranteed max. 0.01%/V line regulation (LM317A)  
Normally, no capacitors are needed unless the device is sit-  
uated more than 6 inches from the input filter capacitors in  
which case an input bypass is needed. An optional output ca-  
pacitor can be added to improve transient response. The  
adjustment terminal can be bypassed to achieve very high  
ripple rejection ratios which are difficult to achieve with stan-  
dard 3-terminal regulators.  
Guaranteed max. 0.3% load regulation (LM117)  
Guaranteed 1.5A output current  
Adjustable output down to 1.2V  
Current limit constant with temperature  
P+ Product Enhancement tested  
Besides replacing fixed regulators, the LM117 is useful in a  
wide variety of other applications. Since the regulator is “float-  
ing” and sees only the input-to-output differential voltage,  
supplies of several hundred volts can be regulated as long as  
80 dB ripple rejection  
Output is short-circuit protected

*Needed if device is more than 6 inches from filter capacitors.  
†Optional—improves transient response. Output capacitors in the range  
of 1μF to 1000μF of aluminum or tantalum electrolytic are commonly used  
to provide improved output impedance and rejection of transients.
