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 the negative complement, see LM137 data sheet. 1 MICROCIRCUIT DATA SHEET MRLM117-K-RH REV 2B0 Industry Part Number NS Part Numbers LM117K LM117KRQMLV Prime Die LM117K Controlling Document SEE FEATURES SECTION Processing Subgrp Description MIL-STD-883, Method 5004 1 2 3 4 5 6 7 8A 8B 9 10 11 Quality Conformance Inspection MIL-STD-883, Method 5005 2 Static tests at Static tests at Static tests at Dynamic tests at Dynamic tests at Dynamic tests at Functional tests at Functional tests at Functional tests at Switching tests at Switching tests at Switching tests at Temp ( oC) +25 +125 -55 +25 +125 -55 +25 +125 -55 +25 +125 -55 MICROCIRCUIT DATA SHEET MRLM117-K-RH REV 2B0 Features - Guaranteed 1.5A output current Adjustable output down to 1.2V Current limit constant with temperature 80 dB ripple rejection Output is short-circuit protected CONTROLLING DOCUMENT: LM117KRQMLV 5962R9951704VYA 3 MICROCIRCUIT DATA SHEET MRLM117-K-RH REV 2B0 (Absolute Maximum Ratings) (Note 1) Power Dissipation Internally Limited Input-Output Voltage Differential +40V, -0.3V Maximum Junction Temperature 150 C Storage Temperature Range -65 C < Ta < +150 C Lead Temperature (Soldering, 10 seconds) 300 C Thermal Resistance ThetaJA (Still Air) (500LF/Min Air flow) 39 C/W 14 C/W ThetaJC ESD Tolerance (Note 3) 1.9 C/W 3000V Note 1: Note 2: Note 3: 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. 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.
