3-TERMINAL POSITIVE LINEAR REGULATOR AZ78LXX
Data Sheet

BCD Semiconductor Manufacturing Limited
General Description
The AZ78LXX series are three terminal positive regu-
lators with several fixed output voltages. These regula-
tors can provide local on card regulation, eliminating
the distribution problems associated with single point
regulation. The AZ78LXX can be used in logic sys-
tems, instrumentation, HiFi, and other solid state elec-
tronic equipment. When used as a Zener diode/resistor
combination replacement, the AZ78LXX usually
results an effective output impedance improvement of
two orders of magnitude, and lower quiescent current.
With adequate heat sinking the AZ78LXX can deliver
100mA output current. Current limiting is included to
limit the peak output current to a safe value. Thermal
protection is also provided. If internal power
dissipation becomes too high for the heat sinking
provided, the thermal shutdown circuit takes over
preventing the IC from overheating.
The AZ78LXX are available in the plastic TO-92 (bulk
or ammo packing), SOIC-8, SOT-223 and SOT-89-3
packages.
