D „ APPLICATION NOTE of LD2117/A ADJUSTABLE The LD2117/A adjustable has a reference voltage of between the OUT and ADJ pins. I ADJ is 7 μA typ. (10 μA R1 is normally fixed to 1.2kΩ. From figure 4 we obtain: V OUT=VREF+R2(IADJ+IR1)=VREF + R2(IADJ+VREF/R1)=VREF(1+R2/R1) + R2 × IADJ. Usually R 2 value is in the range of few K Ω, so the R 2 X I ADJ product could be negle cted; then the above expression becomes: VOUT=VREF(1+R2/R1) For better load regulation, realize a good Kelvin connection of R 1 and R2 is important. Particularly R1 connection must be realized very close to OUT and ADJ pin, while R 2 ground connection must be placed as near as possible to the negative Load pin. Ripple rejecti on can be improved by introducing a 10 μF electrolytic capacitor placed in parallel to the R2 resistor (See Fig. 5) The UTC LD2117/A also supports MLCC. See Fig.6 for adjustable output and Fig.7 for fixed Output IN OUT ADJ UTC LD2117/A 10µF 10µF 1.2kΩ VIN VOUT VREF Fig.4 Adjustable Output Voltage Application Circuit Fig.5 Adjustable Output Voltage Application with improved Ripple Rejection.
