Overview
NJM79L00 3-TERMINAL NEGATIVE VOLTAGE REGULATOR ■ GENERAL DESCRIPTION The NJM79L00 series of 3-Terminal Negative 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 NJM79L00 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.
