SM1116 is also well suited for other applications such as vga cards. SM1116 is guaranteed to have lower than 1.3v dropout at full load current making it ideal to provide well regulated outputs of 1.25v to 5v with up to 12v input supply. * 3-terminal adjustable or f ixed 1.5v,1.8v,2.5v,3.3v,5.0v f e a t u r e s * 1. 3 v max. dropout full load current * output current limiting * good noise rejection * fast transient response * built-in thermal shutdown * communication applications * pc peripheral 01 -jun-2002 rev. a page 1 of 4 http://www.secosgmbh.com/ any changing of specification will not be informed individual r o h s c o m p l i a n t p r o d u c t typical circuit sot-89 3 . 3 v / 0 . 6 a 2.5v/0.6a ref. min. max. ref. min. max. a 4.4 4.6 g 3.00 ref. b 4.05 4.25 h 1.50 ref. c 1.50 1.70 i 0.40 0.52 d 1.30 1.50 j 1.40 1.60 e 2.40 2.60 k 0.35 0.41 f 0.89 1.20 l 5 typ. m 0.70 ref. millimeter millimeter
