description  
LP PACKAGE  
(TOP VIEW)  
The TL317 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.  
INPUT  
OUTPUT  
ADJUSTMENT  
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 TL317 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  
shutdowncan be achieved by clamping ADJUSTMENT to ground, programming the output to 1.2 V, where most  
loads draw little current.  
The TL317C is characterized for operation over the virtual junction temperature range of 0°C to 125°C.
