equivalent circuit block diagram (common to l88m00t series) test circuit (common to l88m00t series) notes: 1. to ensure operational stability, c in and c out should be placed as close to the ic as possible. 2. because the output capacitor c out is set at over 100 f to prevent oscillation at low temperatures, a capacitor that exhibits little change in capacity with temperature variations should be used (such as a tantalum capacitor). 3. when v in is minus (?) and gnd is plus (+) (reversed connection), excessive current flow will occur. start-up circuit reference voltage error amp thermal protector short circuit protector l88m00t l88m00t series no.5839-4/8
1) the allowable power dissipation is 1.0 w (ta = 25c) with no fin attached, but when mounted on a hybrid ic board or printed circuit board, high allowable power dissipation is achieved, despite the compact package. the graph below depicts the relationship between the copper-clad area and allowable power dissipation when mounted on a glass epoxy board (50 50 0.8 tmm 3 ) with a copper thickness of 18 m. 2) pd is the value for when the solder on the surface of the ic heat sink has melted completely and the surface mount is horizontal. 3) please be advised that the flow solder application system (full-heat method) cannot be recommended. lead formings pdmax?ta common for l88m00t series with infinite heat sink mounted on copper-clad area of 2,000 mm 2 mounted on copper-clad area 740 mm 2 mounted on copper-clad area 180 mm 2 mounted on copper-clad area 36 mm 2 no heat sink ambient temperature, ta ? c allowable power dissipation, pd max ? w pdmax?s common for l88m00t series allowable power dissipation, pd max ? w copper-clad area, s ? mm 2 pcb copper-clad area, s ?
