LM337  
3-Terminal 1.5A Negative Adjustable Regulator  
Features  
Description  
• Output current in excess of 1.5A  
The LM337 is a 3-terminal negative adjustable regulator. It  
supplies in excess of 1.5A over an output voltage range of  
-1.2V to - 37V. This regulator requires only two external  
resistor to set the output voltage. Included on the chip are  
current limiting, thermal overload protection and safe area  
compensation.  
• Output voltage adjustable between -1.2V and - 37V  
• Internal thermal overload protection  
• Internal short circuit current limiting  
• Output transistor safe area compensation  
• Floating operation for high voltage applications  
• Standard 3-pin TO-220 package
