LD1117/A LINEAR INTEGRATED CIRCUIT

 APPLICATION NOTE of LD1117/A ADJUSTABLE

The LD1117/A ADJUSTABLE has a reference voltage of between the OUT and ADJ pins. I (120μA max.) and ΔI

is 1μA typ. (5μA max.).

ADJ

is 60μA typ.

ADJ

R1 is normally fixed to 120Ω. From figure 4 we obtain: V

OUT=VREF

Usually R2 value is in the range of few KΩ, so the R2 X I expression becomes: V

+R2(I

+ IR1)=V

REF

product could be neglected; then the above

ADJ

.

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)
