NJM7800
3-TERMINAL POSITIVE VOLTAGE REGULATOR
■
GENERAL DESCRIPTION
The NJM7800 series of monolithic 3-Terminal Positive Voltage
Regulators is constructed using the New JRC Planar epitaxial
process.
These regulators employ internal current-limiting,
thermal-shutdown and safe-area compensation making them
essentially indestructible. If adequate heat sinking is provided, they
can deliver over 1A output current. They are intended as fixed
voltage regulators in a wide range of applications including local (on
card) regulation for elimination of distribution problems associated
with single point regulation. In addition to use as fixed voltage
regulators, these devices can be used with external components to
obtain adjustable output voltages and currents.
