LD1117 series  
Low drop fixed and adjustable positive voltage regulators  
Feature summary  
Low dropout voltage (1V TYP.)  
2.85V Device performances are suitable for  
SCSI-2 active termination  
Output current up to 800 mA  
DPAK  
SO-8  
Fixed output voltage of: 1.2V, 1.8V, 2.5V,  
TO-220  
2.85V, 3.0V, 3.3V, 5.0V  
Adjustable version availability (Vrel=1.25V)  
Internal current and thermal limit  
Available in 1% (at 25°C) and 2% in full  
SOT-223  
temperature range  
Supply voltage rejection: 75dB (typ.)  
The SOT-223 and DPAK surface mount packages  
optimize the thermal characteristics even offering  
a relevant space saving effect. High efficiency is  
assured by NPN 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.  
Description  
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 and TO-220.
