date: 8/3/06 rev h sp78lxx 00ma 3-terminal positive voltage regulator ? 2006 sipex corporation general description the s p78 lxx series are three terminal positive regulators with several fixed output voltages. these regulators can pro - v ide local on - card regulation, eliminating distribution problems associated with single point regulation. the s p78 lx x can be used in logic systems, instrumentation, hifi, and other solid state electronic equipment. when used as a zener diode/resistor combination replacement, the s p78 lxx usually results an effective output impedance improvement of two orders of magnitude, and lower quiescent current. with adequate heat sinking the s p78 lxx can deliver 100 ma output current. current limiting is included to limit the pea k output current to a safe value. thermal protection is also provided. if internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the ic from overheating. the s p78 lxx are available in the plastic to-92, n soic-8, sot -223 and sot -89 packages. features g output current up to 100 ma g fixed output v oltage of 5 v and 12v g output v oltage t olerances of f 5% over the full t emperature range g internal short circuit current-limiting g internal thermal overload protection g no external components g available in lead free, rohs compliant packaging applications g high efficiency linear regulator g post regulation for switching supply g microprocessor power supply g mother board i/o power supply n soic-8 figure . package t ypes of the sp78lxx to-2 sot -223 sot -8 sot -8 package output gnd 2 3 1 input gnd sp78lxx solved by tm 100ma 3-terminal positive voltage regulator
