NJM78L00 Series

3-Terminal Positive Voltage Regulator

The NJM78L00 series of 3-Terminal Positive Voltage Regulator is constructed using the New JRC Planar epitaxial process. These regulators employ internal current-limiting and thermal-shutdown，making them essentially indestructible. If adequate heat sinking is provided，they can deliver up to 100mA 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 NJM78L00 series used as a 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.
