1/17 december 2005 output current up to 100 ma output voltages of -5; -6; -8; -9; -12; -15 v thermal overload protection short circuit protection no external components are required available in either 5% (ac) or 10% (c) selection description the l79l00 series of three-terminal negative regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. if adequate heat-sink is provided, they can deliver up to 100 ma output current. they are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation. in addition, they can be used with power pass elements to make high-current voltage regulators. the l79l00 series used as zener diode/resistor combination replacement, offers an effective output impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower noise. l79l00 series negative voltage regulators figure 1: schematic diagram so-8 sot-89 to-92 rev. 11
l79l00 series 2/17 table 1: absolute maximum ratings (*) our so-8 package used for voltage regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die attach flag. this particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appro- priate area of copper on the printed circuit board is available for heat-sinking. the external dimensions are the same as for t he standard so-8. table 2: thermal data (*) considering 6 cm 2 of copper board heat-sink. figure 2: pin connection (top view, bottom view for to-92) symbol parameter value unit v i dc input voltage v o = -5 to -9 v -30 v v o = -12 to -15 v -35 i o output current 100 ma p tot power dissipation internally limited (*) t stg storage temperature range -40 to 150 c t op operating junction temperature range for l79l00c, l79l00ac 0 to 125 c for l79l00ab -40 to 125 c symbol parameter so-8 to-92 sot-89 unit r thj-case thermal resistance junction-case max 20 15 c/w r thj-amb thermal resistance junction-ambient max 55 (*) 200 c/w so-8 to-92 pin 1 = gnd pin 2 = v in pin 3 = v out sot-89
