(120 a max.) and i adj is 1 a typ. (5 a max.). r 1 is normally fixed to 120 . from figure 9 we obtain: v out = v ref + r 2 (i adj +i r1 ) = v ref + r 2 (i adj +v ref /r 1 ) = v ref (1 + r 2 / r 1 ) + r 2 x i adj . in normal application r 2 value is in the range of few k , so the r 2 x i adj product could not be considered in the v out calculation; then the above expression becomes: v out = v ref (1 + r 2 / r 1 ). in order to have the better load regulation it is important to realize a good kelvin connection of r 1 and r 2 resistors. in particular r 1 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 rejection can be improved by introducing a 10 f electrolytic capacitor placed in parallel to the r 2 resistor (see figure 10 ). figure 10. adjustable output voltage application figure 11. adjustable output voltage application with improved ripple rejection
