DESCRIPTION  
DPAK  
SOT-223  
SO-8  
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.

the  
thermal  
characteristics even offering a relevant space  
saving effect. High efficiency is assured by NPN

LD1117 ADJUSTABLE: APPLICATION NOTE  
The LD1117 ADJUSTABLE has  
stabilized 1.25±0.012V reference voltage between  
the OUT and ADJ pins. I is 60µA typ. (120µA

(1 + R2 / R1).

In order to have the better load regulation it is  
important to realize a good Kelvin connection of  
R1 and R2 resistors. In particular R1 connection  
must be realized very close to OUT and ADJ pin,  
while R2 ground connection must be placed as  
near as possible to the negative Load pin. Ripple  
rejection can be improved by introducing a 10µF  
electrolytic capacitor placed in parallel to the R2  
resistor (see Fig.8).

is 1µA typ. (5µA max.).  
ADJ  
R1 is normally fixed to 120. From figure 7 we  
obtain:

In normal application R2 value is in the range of  
few kohm, so the R2 x I product could not be

considered in the V
