LM137/LM337  
3-Terminal Adjustable Negative Regulators  
n Excellent thermal regulation, 0.002%/W  
n 77 dB ripple rejection  
General Description  
The LM137/LM337 are adjustable 3-terminal negative volt-  
age regulators capable of supplying in excess of −1.5A over  
an output voltage range of −1.2V to −37V. These regulators  
are 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 opti-  
mized for excellent regulation and low thermal transients.  
Further, the LM137 series features internal current limiting,  
thermal shutdown and safe-area compensation, making  
them virtually blowout-proof against overloads.  
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 is short circuit protected  
LM137 Series Packages and Power Capability  
The LM137/LM337 serve a wide variety of applications in-  
cluding local on-card regulation, programmable-output volt-  
age regulation or precision current regulation. The LM137/  
LM337 are ideal complements to the LM117/LM317  
adjustable positive regulators.

†
C1 = 1 µF solid tantalum or 10 µF aluminum electrolytic required for  
stability  
*C2 = 1 µF solid tantalum is required only if regulator is more than 4" from  
power-supply filter capacitor  
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
