L79L Negative voltage regulators Datasheet - production data Description The L79L series of three-terminal negative regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided, H QG U O SH H D D 7 they can deliver up to 100 mA output current.They FD N PRS P 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. 627 The L79L series used as Zener diode/resistor combination replacement, offers an effective output impedance improvement of typically two orders of magnitude, along with lower quiescent Features current and lower noise. Output current up to 100 mA Output voltages of -5 -8 -12 -15 V Thermal overload protection Short-circuit protection No external components are required Available in 5% (AC) or 10% (C) selection April 2014 DocID2511 Rev 17 1/26 This is information on a product in full production. www.st.com 62 72 72Contents L79L Contents 1 Diagram . 3 2 Pin configuration . 4 3 Maximum ratings 5 4 Electrical characteristics . 6 4.1 TO-92 10 4.2 SO-8 11 4.3 SOT-89 . 14 5 Packaging mechanical data 17 5.1 Tape and reel for TO-92 17 5.2 Tape and reel for TO-92 Ammopak . 19 5.3 Tape and reel for SOT-89 . 21 5.4 Tape and reel for SO-8 . 22 6 Order codes 24 7 Revision history . 25 2/26 DocID2511 Rev 17
