LM120/LM320
Series 3-Terminal Negative Regulators
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.
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.
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.
Although primarily intended for fixed output voltage applica-
tions, the LM120 Series may be programmed for higher out-
put voltages with a simple resistive divider. The low quiescent

drain current of the devices allows this technique to be used

*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.
