APPLICATION NOTE of LD1117LI ADJUSTABLE  
The LD1117LI adjustable has a reference voltage of between the OUT and ADJ/GND pins. IADJ is 60µA typ.  
(120µA max.) and ΔIADJ is 1μA typ. (5µA max.).  
R1 is normally fixed to 120Ω.  
From figure 6 we obtain:  
VOUT=VREF+R2(IADJ+IR1)=VREF + R2(IADJ+VREF/R1)=VREF(1+R2/R1) + R2 x IADJ.  
Usually R2 value is in the range of few KΩ, so the R2 X IADJ product could be neglected; then the above  
expression becomes: VOUT=VREF(1+R2/R1)  
For better load regulation, realize a good Kelvin connection of R1 and R2 is important. Particularly R1  
connection must be realized very close to OUT and ADJ/GND 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)
