General Description
The AZ78MXX series are monolithic integrated cir-
cuits designed as fixed-voltage regulators for a wide
variety of applications including local, on-card regula-
tion.
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 0.5A.
The AZ78MXX series are available in two standard
plastic packages: TO-220 and TO-252.
Features
· Output Current up to 0.5A
· 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
