Product Summary

The LT1083CK-5 is a positive adjustable regulator. The LT1083CK-5 is designed to provide 3A, 5A and 7.5A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 1V input to output differential and the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.5V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the output voltage to 1%. Current limit of the LT1083CK-5 is also trimmed, minimizing the stress on both the regulator and power source circuitry under overload conditions.
