L78L Positive voltage regulators Datasheet - production data Description The L78L 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 oncard 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 L78L series used as Zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise. Features Output current up to 100 mA Output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 24 V thermal overload protection Short-circuit protection No external components are required Available in either 4% (A) or 8% (C) selection June 2016 DocID2145 Rev 26 This is information on a product in full production. 1/45 www.st.com Contents L78L Contents 1 Diagram ............................................................................................ 3 2 Pin configuration ............................................................................. 4 3 Maximum ratings ............................................................................. 5 4 5 Electrical characteristics ................................................................ 6 Typical performance ..................................................................... 25 6 Typical application ........................................................................ 27 7 Package information ..................................................................... 29 7.1 TO-92 package information ............................................................. 29 7.2 TO-92 packing information .............................................................. 30 7.3 TO-92 Ammopak packing information ............................................. 32 7.4 SO-8 package information .............................................................. 34 7.5 SO-8 packing information ................................................................ 36 7.6 SOT-89 package information .......................................................... 37 7.7 SOT-89 packing information............................................................ 40 8 Ordering information..................................................................... 41 9 Revision history ............................................................................ 44 2/45 DocID2145 Rev 26 L78L 1 Diagram Diagram Figure 1: Schematic diagram DocID2145 Rev 26 3/45 Pin configuration 2 L78L Pin configuration Figure 2: Pin connection (top view, bottom view for TO-92) Figure 3: Test circuits 4/45 DocID2145 Rev 26 L78L 3 Maximum ratings Maximum ratings Table 1: Absolute maximum ratings Symbol VI IO PD Parameter DC Input voltage Value VO = 3.3 to 9 V 30 VO = 12 to 15 V 35 VO = 18 to 24 V 40 Output current Unit V 100 mA Internally limited Power dissipation TSTG Storage temperature range -65 to 150 TOP Operating junction temperature range for L78LxxAC / L78LxxC 0 to 125 for L78LxxAB -40 to 125 (1) mW C C Notes: (1)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.
