Product Summary
The L78L09ACZ three-terminal positive regulator employs internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided, it can deliver up to 100 mA output current. It is intended as fixed voltage regulator 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, it can be used with power pass elements to make high-current voltage regulators. The L78L09ACZ 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.
