IADJ is 60µA typ. (120µA max.) and IADJ 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) UTC LD1117/A VIN + IN OUT VOUT + GND/ADJ 10µF 10µF R1 120Ω VREF R2 Fig.6 Adjustable Output Voltage Application Circuit UTC LD1117/A VIN IN VOUT OUT GND/ADJ 10µF 10µF R1 120Ω VREF R2 Fig.7 Adjustable Output Voltage Application Circuit (FOR MLCC) UTC LD1117/A VIN + 10µF IN OUT VOUT + GND/ADJ 10µF R1 120Ω VREF + R2 10µF Fig.8 Adjustable Output Voltage Application with improved Ripple Rejection.
