LM120/LM320
Series 3-Terminal Negative Regulators
General Description
The LM120 series are three-terminal negative regulators
with a fixed output voltage of
b
5V,
b
12V, and
b
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
b
1.2V to
b
47V.
The LM120 need only one external componentDa 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 as-
sure satisfactory system operation.
Exceptional effort has been made to make the LM120 Se-
ries immune to overload conditions. The regulators have
current limiting which is independent of temperature, com-
bined with thermal overload protection. Internal current limit-
ing protects against momentary faults while thermal shut-
down prevents junction temperatures from exceeding safe
limits during prolonged 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 quies-
cent drain current of the devices allows this technique to be
used with good regulation.

F aluminum electrolytic may substituted. Values given may be increased
without limit.
For output capacitance in excess of 100
m
F, a high current diode from
input to output (1N4001, etc.) will protect the regulator from momentary
input shorts.
