LM145 LM345 Negative Three Amp Regulator January 1995 LM145 LM345 Negative Three Amp Regulator General Description The LM145 is a three-terminal negative regulator with a fixed output voltage of b5V and up to 3A load current capability This device needs only one external component a compensation capacitor at the output making it easy to apply Worst case guarantees 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 LM145 immune to overload conditions The regulator has current limiting which is independent of temperature combined with thermal overload protection Internal current limiting protects against momentary faults while thermal shutdown prevents junction temperatur
