TO-92 SO-8 SOT-89 Maturity status link L78L L78L Positive voltage regulators Features - Output current up to 100 m A - Output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 24 V thermal overload protection - Short-circuit protection - No external ponents are required - Available in either ± 4% (A) or ± 8% (C) selection 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 m A 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 highcurrent voltage regulators. The L78L series used as Zener diode/resistor bination replacement, offers e improvement along with lower quiescent current and lower noise.
