3-TERMINAL POSITIVE LINEAR REGULATOR
AZ78LXX
General Description
Features
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.
·
·
·
Output Current up to 100mA
Fixed Output Voltages 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
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.
