ADJUSTABLE 3-TERMINAL NEGATIVE VOLTAGE REGULATOR (HIGH

VOLTAGE)

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 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.
