12 APPLICATION NOTE of LD1117/A ADJUSTABLE The LD1117/A adjustable has a reference voltage of between the OUT and ADJ/GND pins. I ADJ is 60µA typ. (120µA max.) and I ADJ is 1μA typ. (5µA max.). R 1 is normally fixed to 120Ω. From figure 6 we obtain: OUT = REF +R 2 (I ADJ +I R1 )= REF + R 2 (I ADJ + REF /R 1 )= REF (1+R 2 /R 1 ) + R 2 x I ADJ. Usually R 2 value is in the range of few KΩ, so the R 2 X I ADJ product could be neglected; then the above expression becomes: OUT = REF (1+R 2 /R 1 ) For better load regulation, realize a good Kelvin connection of R 1 and R 2 is important. Particularly R 1 connection must be realized very close to OUT and ADJ/GND pin, while R 2 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 R 2 resistor (See Fig. 8) Fig.6 Adjustable Application Circuit Fig.7 Adjustable Application Circuit (FOR MLCC) Fig.8 Adjustable Application with improved Ripple Rejection.
