L78L00 series 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 L78L00 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.
The L78L00 series consists of fixed positive voltage regulators designed for applications requiring local or on-card regulation. Key features include internal current limiting, thermal shutdown protection, and the ability to operate without external components in certain configurations. The series is available with output voltages ranging from 3.3V up to 24V.
