description

The LM317 is an adjustable three-terminal

positive-voltage regulator capable of supplying

more than 1.5 A over an output-voltage range of

1.2 V to 37 V. It is exceptionally easy to use and

requires only two external resistors to set the

output voltage. Furthermore, both line and load

regulation are better than standard fixed

regulators. The LM317 is packaged in the KC

(TO-220AB) and KTE packages, which are easy

to handle and use.

ADJUST

TheOUTPUT terminal is inelectrical

contact with the mounting base.

In addition to having higher performance than

fixed regulators, this device includes on-chip

current limiting, thermal overload protection, and

safe-operating-area protection. All overload

protection remains fully functional, even if the

ADJUST terminal is disconnected.

The LM317 is versatile in its applications,

including uses in programmable output regulation

and local on-card regulation. Or, by connecting a

fixed resistor between the ADJUST and OUTPUT

terminals, the LM317 can function as a precision

current regulator. Anoptionaloutputcapacitorcan

be added to improve transient response. The

ADJUST terminal can be bypassed to achieve

very high ripple-rejection ratios, which are difficult

to achieve with standard three-terminal

regulators.

The LM317 is characterized for operation over the

virtual junction temperature range of 0°C to

125°C.
