Product Summary

The LM120 series are three-terminal negative regulatorswith a fixed output voltage of b5V b12V and b15V andup to 15A load current capability Where other voltages arerequired the LM137 and LM137HV series provide an outputvoltage range of b12V to b47VThe LM120 need only one external componenta compen-sation capacitor at the output making them easy to applyWorst case guarantees on output voltage deviation due toany combination of line load or temperature variation as-sure satisfactory system operationExceptional effort has been made to make the LM120 Se-ries immune to overload conditions The regulators havecurrent 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 safelimits during prolonged overloadsAlthough 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 beused with good regulation
