AME78XX
n General Description
The AME78XX is a fixed output positive regulator. The
regulator can provide local on card regulation, eliminating
the distribution problems associated with single point regu-
lation. The AME78XX can be used in logic systems, in-
strumentation, HiFi, and other solid state electronic equip-
ments. When used as a Zener diode/resistor combina-
tion replacement, the AME78XX usually results in an ef-
fective output impedance improvement of two orders of
magnitude, and lower quiescent current.
With adequate heat sinking the AME78XX can deliver
1A output current. Current limiting is included to limit the
peak output current to a safe value.
The AME78XX is available in the plastic TO-220 and
TO-252 packages.
