LM117/LM317A/LM317-N 3-Terminal Adjustable Regulator

Check for Samples: LM117, LM317-N

Normally, no capacitors are needed unless the device

FEATURES

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.

•

Specified 1% Output Voltage Tolerance

(LM317A)

•

Specified Max. 0.01%/V Line Regulation

(LM317A)

•

Specified Max. 0.3% Load Regulation (LM117)

Specified 1.5A Output Current

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.

Adjustable Output Down to 1.2V

Current Limit Constant With Temperature

P⁺Product Enhancement Tested

80 dB Ripple Rejection

Output is Short-Circuit Protected

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

DESCRIPTION

The LM117 series of adjustable 3-terminal positive

voltage regulators is capable of supplying in excess

of 1.5A over a 1.2V to 37V output range. They are

exceptionally easy to use and require only two

external resistors to set the output voltage. Further,

both line and load regulation are better than standard

fixed regulators. Also, the LM117 is packaged in

standard transistor packages which are easily

mounted and handled.

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.

For applications requiring greater output current, see

LM150 series (3A) and LM138 series (5A) data

sheets. For the negative complement, see LM137

series data sheet.

In addition to higher performance than fixed

regulators, the LM117 series 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.

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

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
