by the current flowing through the resistor in the ic. because i fb = v fb /r fb , ?r 2 i fb ? cause of error is as follows. r 2 i fb =r 2 v fb /r fb =v fb r 2 /r fb for better accuracy, choosing r2< r1511x 11 typical characteristics (1) output voltage vs. output current (ta=25oc) r1511x030b r1511x050b 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 0 100 200 300 400 500 600 output current i out (ma) output voltage v out (v) v in =4.5v 5.0v 6.0v 0 1 2 3 4 5 6 0 100 200 300 400 500 600 output current i out (ma) output voltage v out (v) v in =5.5v 6.0v 6.5v r1511x090b r1511x001c 0 1 2 3 4 5 6 7 8 9 10 0 100 200 300 400 500 600 output current i out (ma) output voltage v out (v) v in =9.5v 10.0v 10.5v 0 2 4 6 8 10 12 14 0 100 200 300 400 500 600 output current i out (ma) output voltage v out (v) r 2 =30k ?
