POSITIVE THREE TERMINAL ADJUSTABLE VOLTAGE REGULATOR

General Description

The LM117 adjustable 3-terminal positive voltage regulator is capable of supplying in

excess of 1.5A over a 1.2V to 37V output range. It is exceptionally easy to use and

requires only two external resistors to set the output voltage. Further, both line and

load regulation are better than standard fixed regulators.

In addition to higher performance than fixed regulators, the LM117 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.

Normally, no capacitors are needed unless the device 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.

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).

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 as 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 (3A) and LM138 (5A) data

sheets. For the negative complement, see LM137 data sheet.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

Operating Ratings indicate conditions for which the device is functional, but do not

guarantee specific performance limits. For guaranteed specifications and test

conditions, see the Electrical Characteristics. The guaranteed specifications apply

only for the test conditions listed. Some performance characteristics may degrade

when the device is not operated under the listed test conditions.

Note 2: The maximum power dissipation must be derated at elevated temperatures, and is

dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to

ambient thermal resistance), and TA (ambient temperature). The maximum allowable

power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number

given in the Absolute Maximum Ratings, whichever is lower.

Note 3: Human body model, 1.5K Ohms in series with 100pF.
