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