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 needs only one external component—a
compensation capacitor at the output, making them
easy to apply. Worst case specifies on output voltage
deviation due to any combination of line, load or
temperature variation assure satisfactory 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 prolonged overloads.
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.
