LM120/LM320  
Series 3-Terminal Negative Regulators  
drain current of the devices allows this technique to be used  
with good regulation.  
General Description  
The LM120 series are three-terminal negative regulators with  
a fixed output voltage of −5V, −12V, and −15V, and up to 1.5A  
load current capability. Where other voltages are required, the  
LM137 and LM137HV series provide an output voltage range  
of −1.2V to −47V.  
Features  
Preset output voltage error less than ±3%

Preset current limit  
Internal thermal shutdown  
The LM120 need only one external component—a compen-  
sation capacitor at the output, making them easy to apply.  
Worst case guarantees on output voltage deviation due to any  
combination of line, load or temperature variation assure sat-  
isfactory system operation.  
Operates with input-output voltage differential down to 1V  
Excellent ripple rejection  
Low temperature drift  
Easily adjustable to higher output voltage  
Exceptional effort has been made to make the LM120 Series  
immune to overload conditions. The regulators have current  
limiting which is independent of temperature, combined with  
thermal overload protection. Internal current limiting protects  
against momentary faults while thermal shutdown prevents  
junction temperatures from exceeding safe limits during pro-  
longed overloads.

*Required if regulator is separated from filter capacitor by more than 3 inch-  
es. For value given, capacitor must be solid tantalum. 25 μF aluminum  
electrolytic may be substituted.  
†Required for stability. For value given, capacitor must be solid tantalum. 25  
μF aluminum electrolytic may be substituted. Values given may be increased  
without limit.  
For output capacitance in excess of 100 μF, a high current diode from input  
to output (1N4001, etc.) will protect the regulator from momentary input  
shorts.
