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.

On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25°C and 2% over the full temperature range. Unlike voltage regulators using a PNP transistor as series pass element in which a considerable fraction of the output current is wasted as quiescent current, the LD1083 quiescent current flows almost entirely into the load, improving the efficiency.

Only a 10µF minimum capacitor is required for output stability.
