The LD1117 is a LOW DROP Voltage Regulator  
able to provide up to 800mA of Output Current,  
available even in adjustable version (Vref=1.25V).  
Concerning fixed versions, are offered the  
following Output Voltages: 1.2V,1.8V,2.5V,2.85V,  
3.0V 3.3V and 5.0V. The 2.85V type is ideal for  
SCSI-2 lines active termination. The device is  
supplied in: SOT-223, DPAK, SO-8, TO-220 and  
TO-220FM. The SOT-223 and DPAK surface  
pass transistor. In fact in this case, unlike than  
PNP one, the Quiescent Current flows mostly into  
the load. Only a very common 10µF minimum  
capacitor is needed for stability. On chip trimming  
allows the regulator to reach a very tight output  
voltage tolerance, within ± 1% at 25°C. The  
ADJUSTABLE LD1117 is pin to pin compatible  
with the other standard. Adjustable voltage  
regulators maintaining the better performances in  
terms of Drop and Tolerance.
