LM120 LM320
Series 3-Terminal Negative Regulators
General Description
The LM120 series are three-terminal negative regulators
with a fixed output voltage of
up to 1 5A load current capability Where other voltages are
required the LM137 and LM137HV series provide an output
voltage range of
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 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
