General Description
Features
·
·
·
Constant Output Current up to 1.0A
The AZ78XX series are monolithic integrated circuits
designed as fixed-voltage regulators for a wide variety
of applications including local, on-card regulation.
Fixed Output Voltages of 5V, 6V, 8V, 9V and 12V
Output Voltage Tolerances of ±5% over the Full
Temperature Range
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.
