(10 a max.) and i adj is 0.3 a typ. (2a max.). r 1 is normally fixed to 1.2k ? . from figure 4 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 i adj . usually r 2 value is in the range of few k ? , so the r 2 x i adj product could be negle cted; then the above expression becomes: v out =v ref (1+r 2 /r 1 ) for better load regulation, realize a good kelvin connection of r 1 and r 2 is important. particularly 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 rejecti on can be improved by introducing a 10 f electrolytic capacitor placed in parallel to the r 2 resistor (see fig. 5) the utc ld2117/a also supports mlcc. see fig.6 for adjus table output and fig.7 for fixed output in out adj utc ld2117/a + + 10f 10f r 1 1.2k ? v in v out v ref r 2 fig.4 adjustable output vo ltage application circuit fig.5 adjustable output voltage applic ation with improved ripple rejection.
