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, 100pF discharged through 1.5K Ohms


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.
