3-terminal positive linear regulator az78lxx data sheet 1 mar. 2007 rev. 1. 5 bcd semiconductor manufacturing limited general description the az78lxx series are thr ee terminal positive regu- lators with several fixed output voltages. these regula- tors can provide local on card regulation, eliminating the distribution problems associated with single point regulation. the az78lxx can be used in logic sys- tems, instrumentation, hifi, and other solid state elec- tronic equipment. when used as a zener diode/resistor combination replacement, the az78lxx usually results an effective output impedance improvement of two orders of magnitude, and lower quiescent current. with adequate heat sinking the az78lxx can deliver 100ma output current. current limiting is included to limit the peak 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 az78lxx are av ailable in the plastic to-92 (bulk or ammo packing), soic-8, sot-223 and sot-89-3 packages. features output current up to 100ma fixed output voltages of 5v, 8v, 9v and 12v output voltage tolerances of 5% over the full temperature range internal short circuit current-limiting internal thermal ov erload protection no external components applications high efficiency linear regulator post regulation for switching supply microprocessor power supply mother board i/o power supply soic-8 figure 1. package types of the az78lxx to-92 sot-223 sot-89-3 to-92 ammo packing
