Description
The Bay Linear LM78LXX is integrated linear positive
regulator with three terminals. The LM78LXX offer several
fixed output voltages making them useful in wide range of
applications. When used as a zener diode/resistor co mbination
replacement, the LM78LXX usually results in an effective
output impedance improvement of two orders of magnitude,
lower quiescent current. The voltages available allow the
LM78LXX to be used in logic systems, instrumentation, HIFI,
and other solid-state electronic equipment.
The LM78LXX is available in the plastic TO-92 (Z) package,
