PS 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.

In addition to higher performance than fixed

regulators, this regulator offers full 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.

OUTPUT

ADJUSTMENT

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

shutdown can 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.

The TL317 is characterized for operation over the virtual-junction temperature range of −20°C to 125°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
