LT1083CP-12#PBF DescripTion

The LT®1083 series of positive adjustable regulators aredesigned to provide 3A, 5A and 7.5A with higher efficiencythan currently available devices. All internal circuitry isdesigned to operate down to 1V input to output differentialand the dropout voltage is fully specified as a functionof load current. Dropout is guaranteed at a maximum of1.5V at maximum output current, decreasing at lower loadcurrents. On-chip trimming adjusts the output voltage to1%. Current limit is also trimmed, minimizing the stresson both the regulator and power source circuitry underoverload conditions.The LT1083 series devices are pin compatible with olderthree-terminal regulators. A 10µF output capacitor isrequired on these new devices; however, this is usuallyincluded in most regulator designs.Unlike PNP regulators, where up to 10% of the output cur-rent is wasted as quiescent current, the LT1083 quiescentcurrent flows into the load, increasing efficiency.
