General Description
MDLM137HV-K General Description
The LM137HVK is an adjustable 3-terminal negative voltage regulator capable of supplying in excess of -1.5A 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 LM137HVK features internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads.
The LM137HVK serves a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM137HVK is an ideal complement to the LM117HVK adjustable positive regulator.

(Note 3).............................................................................................4000V
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.
