Direct Replacement for Motorola MC79L
Series
description
This series of fixed negative-voltage integrated-circuit
voltage regulators is designed for a wide range of
applications.These include on-card regulation for
eliminationof noise and distribution problems
associatedwith single-point regulation. In addition,
they can be used to control series pass elements to make high-current voltage-regulator circuits. One of these
regulators can deliver up to 100 mA of output current. The internal current-limiting and thermal-shutdown features
make them essentially immune to overload. When used as a replacement for a zener-diode and resistor combination,
these devices can provide ef
current.
