Data Sheet
3-TERMINAL POSITIVE LINEAR REGULATOR
AZ78LXX
General Description
Features
The AZ78LXX series are three terminal positive regulators with several fixed output voltages. These regulators can provide local on card regulation, eliminating
the distribution problems associated with single point
regulation. The AZ78LXX can be used in logic systems, instrumentation, HiFi, and other solid state electronic 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.
·
·
·
·
·
·
Output Current up to 100 mA
Fixed Output Voltage of 5V, 8V, 9V and 12V
Output Voltage Tolerances of ± 5% over the Full
Temperature Range
Internal Short Circuit Current-Limiting
Internal Thermal Overload Protection
No External Components
Applications
With adequate heat sinking the AZ78LXX can deliver
100 mA 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.
