| L79L00 SERIES NEGATIVE VOLTAGE REGULATORS s s s s s s 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 SO-8 SOT-89 DESCRIPTION The L79L00 series of three-terminal positive 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 TO-92 output impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower noise. SCHEMATIC DIAGRAM July 2003 1/15 L79L00 SERIES ABSOLUTE MAXIMUM RATINGS Symbol VI IO Ptot Tstg Top DC Input Voltage Output Current Power Dissipation Storage Temperature Range Operating Junction Temperature Range For L79L00C, L79L00AC For L79L00AB Parameter VO = -5 to -9 V VO = -12 to -15 V Value -30 -35 100 Internally Limited (*) -40 to 150 0 to 125 -40 to 125 C C C Unit V mA (*) 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 appropriate area of copper on the printed circuit board is available for heat-sinking. The external dimensions are the same as for the standard SO-8.
