MICROCIRCUIT DATA SHEET Original Creation Date: 07/12/95 Last Update Date: 04/16/99 Last Major Revision Date: 04/02/99 MDLM137HV-H REV 1A1 ADJUSTABLE, 3-TERMINAL NEGATIVE VOLTAGE REGULATOR (HIGH VOLTAGE) General Description The LM137HVH 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 -47V. 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. Further, the LM137HVH features internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads. The LM137HVH serves a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM137HVH is an ideal complement to the LM117HVH adjustable positive regulator.

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.
