3-TERMINAL POSITIVE LINEAR REGULATOR

General Description

Features

AZ78LXX

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 · High Efficiency Linear Regulator

100mA output current. Current limiting is included to · Post Regulation for Switching Supply

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.
