MICROCIRCUIT DATA SHEET Original Creation Date: 09/21/00 Last Update Date: 07/14/04 Last Major Revision Date: 07/07/04 MRLM137-X-RH REV 2A0 3-TERMINAL VOLTAGE REGULATOR, -37 VOLTS < VO < -1.25 VOLTS AT 0.5A GUARANTEED TO 30k rd(Si) TESTED TO MIL-STD-883, METHOD 1019 General Description The LM137H is an adjustable 3-terminal negative voltage regulator capable of supplying in excess of -0.5A over an output voltage range of -1.2V to -37V. This regulator is exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Futher, the LM137H features internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads. The LM137H serve a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM137H is an ideal complement to the LM117H adjustable positive regulator.

Operating Rating 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. For the CERAMIC SOIC device to function properly, the "Output" and "Output/Sense" pins must be connected on the users printed circuit board. 3 MICROCIRCUIT DATA SHEET MRLM137-X-RH REV 2A0 (Continued) Note 4: Note 5: The package material for these devices allows much improved heat transfer over our standard ceramic packages. In order to take full advantage of this improved heat transfer, heat sinking must be provided between the package base (directly beneath the die), and either metal traces on, or thermal vias through, the printed circuit board. Without this additional heat sinking, device power dissipation must be calculated using junction-to-ambient, rather than junction -to-case, thermal resistance. It must not be assumed that the device leads will provide substantial heat transfer out the package, since the thermal resistance of the leadframe material is very poor, relative to the material of the package base. The stated junction-to-case thermal resistance is for the package material only, and does not account for the additional thermal resistance between the package base and the printed circuit board. The user must determine the value of the additional thermal resistance and must combine this with the stated value for the package, to calculate the total allowed power dissipation for the device.
