NJM78L00
3-TERMINAL POSITIVE VOLTAGE REGULATOR
■ GENERAL DESCRIPTION
The NJM78L00 series of 3-Terminal Positive Voltage Regulators
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.
