Product overview

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, 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 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 current and lower noise.

  • All features

    • 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
    • Output tolerance + 4%
