LM120/LM320-N Series 3-Terminal Negative Regulators  
Check for Samples: LM120, LM320-N

FEATURES  
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 prolonged overloads.

Excellent Ripple Rejection  
Although primarily intended for fixed output voltage  
applications, the LM120 Series may be programmed  
for higher output voltages with a simple resistive  
divider. The low quiescent drain current of the  
devices allows this technique to be used with good  
regulation.  
Low Temperature Drift  
Easily Adjustable to Higher Output Voltage  
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.

Current  
The LM120 need only one external component—a  
compensation capacitor at the output, making them  
easy to apply. Worst case specifications on output  
voltage deviation due to any combination of line, load  
or temperature variation assure satisfactory system  
operation.

Typical Applications  
*Required if regulator is separated from  
filter capacitor by more than 3 inches. 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.
