LM137HV/LM337HV  
3-Terminal Adjustable Negative Regulators  
(High Voltage)  
General Description  
Features  
n Output voltage adjustable from −1.2V to −47V  
The LM137HV/LM337HV are adjustable 3-terminal negative  
voltage regulators capable of supplying in excess of −1.5A  
over an output voltage range of −1.2V to −47V. These regu-  
lators are exceptionally easy to apply, requiring only 2 exter-  
nal resistors to set the output voltage and 1 output capacitor  
for frequency compensation. The circuit design has been op-  
timized for excellent regulation and low thermal transients.  
Further, the LM137HV series features internal current limit-  
ing, thermal shutdown and safe-area compensation, making  
them virtually blowout-proof against overloads.  
n 1.5A output current guaranteed, −55˚C to +150˚C  
n Line regulation typically 0.01%/V  
n Load regulation typically 0.3%  
n Excellent thermal regulation, 0.002%/W  
n 77 dB ripple rejection  
n Excellent rejection of thermal transients  
n 50 ppm/˚C temperature coefficient  
n Temperature-independent current limit  
n Internal thermal overload protection  
n P+ Product Enhancement tested  
n Standard 3-lead transistor package  
n Output short circuit protected  
The LM137HV/LM337HV serve a wide variety of applica-  
tions  
including  
local  
on-card  
regulation,  
programmable-output voltage regulation or precision current  
regulation. The LM137HV/LM337HV are ideal complements  
to the LM117HV/LM317HV adjustable positive regulators.  
Typical Applications

=
C1 1 µF solid tantalum or 10 µF aluminum electrolytic required for stability. Output capacitors in the range of 1 µF to 1000 µF of aluminum or tantalum  
electrolytic are commonly used to provide improved output impedance and rejection of transients.
