IADJ is 60μA typ. (120μA max.) and ΔIADJ is 1μA typ. (5μA max.). R1 is normally fixed to 120Ω. From figure 4 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 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. 5) UTC LD1117/A VIN 10μF + IN ADJ R1 120Ω VREF OUT + 10μF VOUT R2 FIG.4 Adjustable Output Voltage Application Circuit FIG.5 Adjustable Output Voltage Application with improved Ripple Rejection.
