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. KD1083 7.5A LOW DROP POSITIVE VOLTAGE REGULATOR ADJUSTABLE AND FIXED This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. SCHEMATIC DIAGRAM TO-220 D2PAK PRELIMINARY DATA |
