DESCRIPTION
PW PACKAGE
The
TL317
is
an
adjustable
three-terminal
(TOP VIEW)
positive-voltage regulator capable of supplying 100
mA over an output-voltage range of 1.25 V to 32 V. It
is exceptionally easy to use and requires only two
external resistors to set the output voltage.

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
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.
