Output Current of 3A, 5A or 7.5A  
Operates Down to 1V Dropout  
The LT1083 series of positive adjustable regulators are  
designedtoprovide3A, 5Aand7.5Awithhigherefficiency

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.
