FEATURES  
DESCRIPTION  
Three-Terminal 3.3V, 3.6V, 5V and 12V  
Output Current of 3A, 5A or 7.5A  
Operates Down to 1V Dropout  
The LT1083 series of positive adjustable regulators are  
designedtoprovide3A, 5Aand7.5Awithhigherefficiency  
than currently available devices. All internal circuitry is  
Guaranteed Dropout Voltage at Multiple Current Levels designedtooperatedownto1Vinputtooutputdifferential  
Line Regulation: 0.015%  
and the dropout voltage is fully specified as a function of  
load current. Dropout is guaranteed at a maximum of 1.5V  
at maximum output current, decreasing at lower load  
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.  
Load Regulation: 0.1%  
100% Thermal Limit Functional Test  
Adjustable Versions Available

APPLICATIONS  
High Efficiency Linear Regulators  
The 1083 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.  
Post Regulators for Switching Supplies  
Constant Current Regulators  
Battery Chargers  
DEVICE  
OUTPUT CURRENT*  
Unlike PNP regulators, where up to 10% of the output  
current is wasted as quiescent current, the LT1083 quies-  
cent current flows into the load, increasing efficiency.
