3-TERMINAL NEGATIVE VOLTAGE REGULATOR

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

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.
