FEATURES  
DESCRIPTION  
The LT®1086 is designed to provide 1.5A with higher  
efficiency than currently available devices. All internal  
circuitry is designed to operate down to 1V input-to-  
output differential and the dropout voltage is fully speci-  
3-Terminal Adjustable or Fixed  
2.85V, 3.3V, 3.6V, 5V, 12V  
Output Current of 1.5A, (0.5A for LT1086H)  
Operates Down to 1V Dropout  
Guaranteed Dropout Voltage at Multiple Current Levels fied as a function of load current. Dropout is guaranteed at  
Line Regulation: 0.015%  
a maximum of 1.5V at maximum output current, decreas-  
ing at lower load currents. On-chip trimming adjusts the  
reference/ouput 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  
U
APPLICATIONS  
TheLT1086ispincompatiblewitholder3-terminaladjust-  
able regulators. A 10µF output capacitor is required on  
these new devices; however, this is usually included in  
most regulator designs.  
SCSI-2 Active Terminator  
High Efficiency Linear Regulators  
Post Regulators for Switching Supplies  
Constant Current Regulators  
Battery Chargers  
A 2.85V output version is offered for SCSI-2 active termi-  
nation. For surface mount applications see the LT1117-  
2.85datasheet. Forhighcurrentorlowerdropoutrequire-  
ments see the LT1123-2.85 data sheet.  
Microprocessor Supply  
Unlike PNP regulators, where up to 10% of the output  
current is wasted as quiescent current, the LT1086 quies-  
cent current flows into the load, increasing efficiency.
