POSITIVE THREE TERMINAL ADJUSTABLE VOLTAGE REGULATOR  
General Description  
The LM117 adjustable 3-terminal positive voltage regulator is capable of supplying in  
excess of 0.5A over a 1.2V to 37V output range. It is exceptionally easy to use and  
requires only two external resistors to set the output voltage. Further, both line and  
load regulation are better than standard fixed regulators.  
In addition to higher performance than fixed regulators, the LM117 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 terminal is disconnected.  
Normally, no capacitors are needed unless the device is situated more than 6 inches from  
the input filter capacitors in which case an input bypass is needed. An optional output  
capacitor 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  
standard 3-terminal regulators.  
Besides replacing fixed regulators, the LM117 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, (i.e., avoid short-circuiting the  
output).  
Also, it makes an especially simple adjustable switching regulator, 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.
