AME, Inc. AME78LXX n General Description 100mA Positive Linear Regulator n Functional Block Diagram The AME78LXX is a fixed output positive regulator. The regulator can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The AME78LXX can be used in logic systems, instrumentation, HiFi, and other solid state electronic equipments. When used as a Zener diode/resistor combination replacement, the AME78LXX usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. Input Current Limiting Amplifier Thermal Protection 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. Output Error Amp.
