FEATURES  
DESCRIPTIO  
The LT®1117 is a positive low dropout regulator designed  
to provide up to 800mA of output current. The device is  
availableinanadjustableversionandfixedoutputvoltages  
of 2.85V, 3.3V and 5V. The 2.85V version is designed  
specifically to be used in Active Terminators for the SCSI  
bus.Allinternalcircuitryisdesignedtooperatedownto1V  
input to output differential. Dropout voltage is guaranteed  
at a maximum of 1.2V at 800mA, decreasing at lower load  
currents. On chip trimming adjusts the reference/output  
voltage to within ±1%. Current limit is also trimmed in  
order to minimize the stress on both the regulator and the  
power source circuitry under overload conditions.

High Efficiency Linear Regulators

The low profile surface mount SOT-223 package allows  
the device to be used in applications where space is  
limited.TheLT1117requiresaminimumof10µFofoutput  
capacitance for stability. Output capacitors of this size or  
larger are normally included in most regulator designs.  
5V to 3.3V Linear Regulators  
Unlike PNP type regulators where up to 10% of the output  
current is wasted as quiescent current, the quiescent  
current of the LT1117 flows into the load, increasing  
efficiency.
