AX1006 is also well suited for other applications such as vga cards. AX1006 is g uaranteed to have lower than 1. 2 v dropout at full load current making it ideal to provi de well - regulated outputs of 1.25 to 5.0 with vout+1.2 v to 1 2 v input supply voltage . ? features - 1. 2 v maximum dropout at full load current - fast transient response - output current limiting - built - in thermal shutdown - good noise rejection - mlcc capacitors are avai lable . - 3 - terminal adjustable or fixed 1.2v, 1.5v, 1.8v, 2.5v, 3.3v, 5.0v - package: sot - 23 - 3l . ? application circuit fixed output adj output v i n = 5 v v o u t = 3 . 3 v c 2 0 . 2 u f a x 1 0 0 6 - 3 3 g n d v o u t v i n c 1 0 . 2 u f v i n = 5 v v o u t = 3 . 3 v c 2 0 . 2 u f a x 1 0 0 6 - a d j a d j v o u t v i n c 1 0 . 2 u f r 1 2 4 0 r 2 3 9 0 v v r r v v ref ref out 250 . 1 ); 1 2 1 ( ? ? ? ?
