n General Description
1A Positive Linear Regulator
n Functional Block Diagram
The AME78XX is a fixed output positive regulator. The
regulator can provide local on card regulation, eliminating
the distribution problems associated with single point regulation. The AME78XX can be used in logic systems, instrumentation, HiFi, and other solid state electronic equipments. When used as a Zener diode/resistor combination replacement, the AME78XX usually results in an effective output impedance improvement of two orders of
magnitude, and lower quiescent current.

Amplifier
Thermal
Protection
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.
