DESCRIPTION

The KD1083 is a low drop linear voltage regulator, proposed both in adjustable and fixed version and designed for use in applications requiring output currents up to 7.5A. Dropout voltage is guaranteed not to exceed 1.4V at maximum output current while it decreases at lighter loads. The KD1083 also features an on-chip output current limit function and a thermal shutdown protection with hysteresis, preventing from excessive power dissipation in case of insufficient heatsinking. The KD1083 is fully pin to pin compatible with the older 3-terminal adjustable regulators, but it has better performances in terms of drop and output voltage precision.
