and the dropout voltage is fully specified as a function  
of load current. Dropout is guaranteed at a maximum of  
1.5Vatmaximumoutputcurrent, decreasingatlowerload  
currents. On-chip trimming adjusts the output voltage to  
1%. Current limit is also trimmed, minimizing the stress  
on both the regulator and power source circuitry under  
overload conditions.

High Efficiency Linear Regulators  
The LT1083 series devices are pin compatible with older  
three-terminal regulators. A 10µF output capacitor is  
required on these new devices; however, this is usually  
included in most regulator designs.

OUTPUT CURRENT*  
Unlike PNP regulators, where up to 10% of the output cur-  
rent is wasted as quiescent current, the LT1083 quiescent  
current flows into the load, increasing efficiency.
