1 / 29 page August 2008 Rev 16 1/29 29 L78LxxAB L78LxxAC - L78LxxC Positive voltage regulators 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 ±5% (AC) or ±10% (C) selection Description The L78Lxx 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 L78Lxx 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.
