Ordering Information

Note: XX: Voltage Output. 05(5V); 08(8V), 09(9V), 12(12 BM78xxAS, the marking is AS78XX, in datacode, it is BMabcdef(ab=year, cd=weeks, ef=producing number) BM7805L, the marking is L7805CVA Typical Application Note 1: CIN is required if regulator is located an appreciable dist ance from power supply filter. Note 2: COUT is needed for stability; and it also does improve transient response. Values of less than 0.1u F could cause instability. Note 3: When choose BM7805L,you can get better BM78XX Series 1 3 V IN V OUT C OUT 0.1uF (Note2) C IN 0.33uF (Note1) TO-252 FRONT VIEW
