The AME78LXX 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 AME78LXX can be used in logic systems,
instrumentation, HiFi, and other solid state electronic
equipments. When used as a Zener diode/resistor com-
bination replacement, the AME78LXX usually results in
an effective output impedance improvement of two orders
of magnitude, and lower quiescent current.
With adequate heat sinking the AME78LXX can deliver
100mA output current. Current limiting is included to limit
the peak output current to a safe value.
The AME78LXX is available in the plastic TO-92, SO-8
and SOT-89 packages.
