Overview of L79L05ACUTR

DescriptionThe 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.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• Available in ±5% (AC) or ± 10% (C) selection
