BCD Semiconductor Manufacturing Limited
General Description
The AZ78XX series are monolithic integrated circuits
designed as fixed-voltage regulators for a wide variety
of applications including local, on-card regulation.
This series of regulators are complete with internal
current limiting, thermal shutdown protection, and
safe-area compensation which make them virtually
immune from output overload. If adequate heat sink-
ing are provided, these regulators can deliver output
currents up to 1.0A.
The AZ78XX series are available in two standard plas-
tic packages: TO-220 and TO-252.
Features
Output Current up to 1.0A
Fixed Output Voltages of 5V, 6V, 8V, 9V and 12V
Output Voltage Tolerances of 5% over the Full
Temperature Range
Internal Short Circuit Current-limiting
Internal Thermal Overload Protection
Applications
Consumer Electronics
Microprocessor Power Supply
Mother Board I/O Power Supply

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.
