APPLICATION NOTE of LD1117/A ADJUSTABLE
LINEAR INTEGRATED CIRCUIT
The LD1117/A ADJUSTABLE has a reference voltage of between the OUT and ADJ pins. IADJ is 60A typ. (120A max.) and IADJ is 1A typ. (5A max.). R1 is normally fixed to 120. 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 K, 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 10F electrolytic capacitor placed in parallel to the R2 resistor (See Fig. 5) UTC LD1117/A VIN 10F + IN ADJ R1 120 VREF OUT + 10F VOUT
