MDLM137HV-H REV 1A1 MICROCIRCUIT DATA SHEET
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.

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.
